The vacuum test pump LR-Cal 2941 is used to generate vacuum (negative pressure) for checking, adjusting and calibrating mechanical and electronic pressure measuring instruments by comparative measurements. These vacuum tests may be carried out in laboratories, workshop or on site at the measuring point. If the instrument to be tested and a sufficiently accurate reference measuring instrument are connected up to the test pump, the same vacuum is applied to the two measuring instruments when the vacuum test pump LR-Cal 2941 is is operated. By comparing the two measure valuses at random pressure values, the accuracy can be verified or the instrument under test can be adjusted. Despite its compact dimensions, the vacuum test pump LR-Cal 2941 is easy to operate and allows for exact generation of the required test vacuum. The LR-Cal 2941 is fitted with a fine adjustment valve for precise adjustment of vacuum. Pressure connection is made with 4 mm hose, a T-piece wich quick-coupling and a piece of hose is included in standard delivery.

Proven primary pressure standard Deadweight Tester / Pressure Balances are the most accurate instrument available on the market for the calibration of electronic or mechanical pressure measuring instruments. The direct measurement of the pressure (p = F / A), as well as the use of high-quality materials enable a very small measurement uncertainty, in conjunction with an excellent long-term stability of 5 years (recommended in accordance with German Calibration Service DAkkS). The deadweight tester / pressure balance has therefore been used for years in factory and calibration laboratories in national institutes, research laboratories and in industry. Stand-alone operation Due to its integrated pressure generation and the pure mechanical measuring principle, the model LR-Cal LDW-P is ideal for on-site use for maintenance and service. Basic principle Pressure is defined as the quotient of force and area. The core component of the model LR-Cal LDW-P is therefore a very pecisely manufatured piston-cylinder-system, which is loaded with masses in order to generate the individual test points. The masses applied are proportional to the target pressure and this is achieved through optimally graduated weights. As standard, these masses are manufactured to the standard gravity (9.80665 m/s²), though the can be manufactured to a specific location (gravity) and also DAkkS-calibrated. Easy operation Depending on the instrument version the pressure is set via an integrated pump or via an external pressure supply by the use of control valves. For fine adjustment a very precisely adjustable spindle pump with a precision spindle running only within the pump body is mounted. As soon as the measuring system reaches equilibrium, there is a balance of forces between the pressure and the mass load applied. The excellent quality of the system ensures that this pressure remains stable over several minutes, so that the pressure value for comparative measurements can be read without any problems, or also so that more complex adjustments can be carried out on the item under test.

The wireless mini-logger from MSR stores over one million measured values. By integrating it into a WLAN/WiFi network, the MSR145W2D can be used in practically any kind of measurement applications.
The WiFi data logger is an all-round talent when it comes to sensor technology: You can choose various internal sensors as well as up to five external sensors or connections. The FlexConnector offers the highest possible flexibility. The intelligent plug-in connection facilitates customer-specific adaptation of the desired FlexSensors.
No wiring costs and no time-consuming manual reading of measured values. Measured data can even be sent from places with difficult access. Integration either into an existing WiFi or via an access point, by means of mobile network access where required, into a separate wireless network.
When it comes to observing environmental conditions over a longer period of time, in many cases it is quite sufficient to transmit the collected data via WiFi once or twice a day. When configuring the MSR145W2D, you can set the time windows during which the data logger should connect to the WiFi network. The WiFi connection is thus only activated when it is needed – which has a positive effect on the battery life of the data logger.
With the MSR145W2D you have the option of using the MSR LocalCloud to store, manage and export the data either locally on your (company’s) own server or in the web-based cloud solution MSR SmartCloud. Via web browser you can view the measured values during operation.
In order to gain knowledge about the movement activity of dairy goats, MSR145W2D data loggers with acceleration sensors are used in a scientific research project. The loggers record the animals’ activities for 24 hours. The data transmission via WiFi takes place energy-savingly only once a day – when the goats are in the barn. This energy-saving data transmission allows the battery to run for more than 5 months. Should the WiFi connection fail, the data remain securely stored in the logger and can also be read out via USB.
For test measurements, it is often necessary to monitor measurement data in real time. In this case, the MSR145W2D is configured by the user so that the data is permanently sent to the WiFi network. Although the uninterrupted transmission of data results in higher power consumption, which affects the mobile operating time of the data logger, the data can be viewed immediately using MSR LocalViewer. For further processing, the measurement data can be sent to the cloud if required.
To determine load values, wireless MSR145W2D data loggers run along the production line at a beverage manufacturer. The measurement data is transmitted in real time via WiFi. Critical values are detected immediately. The recorded data not only help to gain insights into possible causes of increased wear in the production line, the implemented measures can subsequently be checked for their effectiveness with the data loggers
measurement rate up to 1000/s per channel · optionally temperature, humidity, air pressure, position and light sensors
Four integrated analogue inputs, a high measurement rate of 1000/s per channel and its gigantic memory capacity, all packed into a small format are the key characteristics of the swiss made MSR160 data logger.
The analogue inputs of the logger can be used for conventional sensors with analogue outputs (e.g. voltage, current, CO2 etc). The analogue inputs allow voltage and milliamp current to be measured at high data rates up to 1,000 readings per second. A multiple output switching power supply is also provided. Optionally, the MSR160 can be fitted with additional temperature, humidity, pressure, acceleration or light sensors.
The rugged but leightweight data logger records over 2,000 000 measurement parameters. With the optional microSD card you can expand the memory capacity to over one billion measurement parameters. All saved data can be rapidly transferred to a PC or laptop via the USB interface. The user-friendly data acquisition and analysis software is supplied free along with the data logger.
shock data logger with 2 acceleration sensors ±15 g and ±200 g · temperature, humidity, air pressure and light sensors available · stores 2 million total readings · air cargo approved
Whether it be to verify questions of liability, detect damage early or to optimise packaging: The MSR175 data logger accurately records critical transport events such as shocks, jolts or fluctuations in temperature, pressure or humidity and provides clarity with objective measured data.
The two digital 3-axis-acceleration sensors (± 15 g and ± 200 g) integrated in the MSR175 record shocks at a measurement frequency of up to 6400/s. The storage capacity of over 2 million measured values is sufficient to record at least 1,000 shocks (230 mAh Li-Po battery) or approximately 1,000 shocks (3.6 V, 7700 mAh Li-SOCI2 battery), depending on the type variant.
In addition, the transportation data logger measures and records temperature profiles from -20° to +65 °C. Further type variants of the MSR175 are available with internal humidity, air pressure and light sensors.
The software package for the MSR175 includes 3 programs: MSR175 Dashboard, MSR ReportGenerator and MSR ShockViewer. The MSR Dashboard allows you to configure the logger with just a few mouse clicks. The data recorded can be quickly transferred to a computer via the USB port. A single click on the MSR ReportGenerator is sufficient to call up a compact report. For a detailed measured data analysis, the MSR ShockViewer, which is integrated in the MSR175 software package as a free basic version, is at your disposal.
