The 9FLD series is a special version of the 9LD pressure transmitter. The flanged housing can be mounted using an O-ring or welded on. As with all D-line products, the chip-in-oil technology developed by KELLER is used here, uniting a pressure measuring cell, digital temperature compensation and signal processing in a compact housing made of stainless steel or Hastelloy.The I2C interface and the low supply voltages make it easy to integrate in microcontroller-based systems. The extremely low power consumption is ideal for battery-operated devices. The D line is perfect for IoT solutions.
The pressure transducers of the 10L series have a robust housing of stainless steel, giving them optimum long-term stability for a range of OEM applications. The metal diaphragm is welded on front-flush and gap-free, separating off the piezoresistive pressure sensor made of silicon from the measuring medium. Every pressure transducer is measured over the entire pressure and temperature profile and is supplied with a detailed calibration sheet.

KOBOLD pressure sensors series PDD are cost-effective electronic pressure switches with digital indication of actual pressure. Two switch points, on / off-switch delay and hysteresis, are within the measuring range and are programmable.
A piezzo resistive ceramic sensor is used. The units can be used where high switching accuracy is needed. Long-term stability, repeatability and the compact and robust design makes them ideal for use in OEM applicaionts.
The electronic KOBOLD pressure transmitter and switch PSD with integrated display is used for continuous pressure measurement and monitoring and allows simple switching point programming without pressurisation. For each switching point, the contact function (NC contact/ NO contact), the reset points and the switching function (hysteresis/window function) can be programmed. Switching currents ranging up to 500 mA can be switched by the output transistors. The long-term proven thin-film cells give this pressure switch very good repeating accuracy and a long life, even at high load alternation. The rotating display and rotating electrical connection allow the switch also to be used under extreme mounting conditions. All wetted parts are made of stainless steel, making almost all media restrictions unnecessary for the electronic pressure transmitter/switch. The electronic pressure transmitter/switch PSD can be used for a wide range of measuring tasks in hydraulics and pneumatics.
The pressure test pump LR-Cal LPP 700 is used to generate pressure for checking, adjusting and calibrating mechanical and electronic pressure measuring instruments by comparative measurements. These pressure 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 pressure is applied to the two measuring instruments when the pressure test pump LR-Cal LPP 700 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 pressure test pump LR-Cal LPP 700 is easy to operate and allows for exact generation of the required test pressures The LR-Cal LPP 700 is fitted with a fine adjustment valve for a precise adjustment of pressures. The reference instrument is screwd directly on the top of the pump and the unit under test is connected by means of the connection tube incorporating an adapter 1/4" BSP female thread (freely rotating), contained in the scope of delivery.
The Series 1000 and 2000 are a range of extra large 3 to 5 digit LED array displays, 125 mm digit height, designed to be used in process / temperature / weighing applications where high visibility and distant viewing is required. Using high intensity wide angle LED's in an IP65 enamelled steel housing ensures clear viewing distances of greater than 50 metres. For high ambient temperature conditions, an optional special coated glass window is available. Typical applications include downtime, time and production control in large factories, the indication of load cell inputs / crane overload protection, process signals such as temperature, pressure, level, and AC or DC voltages and currents. For electrical specifications, input signal details, as well as the terminal connector assignments in the Extra Large Display, see the individual indicator operating manuals (e.g. Model 4001). Standard DPM indicators are used and internally fitted for the internal signal conversion for the Extra Large Displays. (Models ending in a 2)
