Larger unit quantities can also be programmed with tailored device functions in preparation for their subsequent use. The dV2 manometers are available with a range of housing designs and process connections, and can also be obtained as an OEM module.
The SGH wire-actuated encoder measures the absolute, direct cylinder stroke in the hydraulic cylinder. Cost-intensive drilling of the piston is no longer required thanks to the new measurement system. As a result there are lower integration costs compared with other measurement systems and weakening of the piston is effectively avoided. The highlight: The measurement system can even be used in telescopic cylinders! In the framework of SPS IPC Drives 2015, exhibition and online visitors nominated the SGH10 as the winner of the DirectIndustry i-NOVO Award in the TECH category.

Absolute position sensor for hydraulic cylinders, telescopic cylinders, and piston accumulators, based on the tried and tested wire-actuated sensor technology. Durable, reliable, and robust. Developed with the know-how of over 30 years of experience in wire-actuated sensor technology.
The SGH10 wire-actuated encoder measures the absolute direct cylinder stroke in a hydraulic cylinder. The new measuring system eliminates costly boring of the piston. As a result, integration costs are reduced compared to other measuring systems and a possible weakening of the piston is avoided effectively. The highlight of the SGH10L: Thanks to its unique lateral installation, the SGH10L can also be used in almost unsolvable applications, regardless of whether for applications in which no stoke lost can be accepted, extremely small piston diameters or in the case of cylinders with mechanical end position cushioning.
Absolute position display with communication interface for linear or slide adjustment intuitively guides the operator to the correct machine setting when changing products or changing formats. Readability is optimized for intuitive user prompting: The backlit display clearly shows the setpoint and actual value, and the two LEDs clearly indicate the direction in which the adjustment must be made. The IO link interface enables easy and reliable integration into modular machines.
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 DKD/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-H 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-H 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 In the stable instrument base, the integrated priming pump and the 250 ml tank enable large test volumes to be easily filled and pressurised. For further pressure increases and find adjustment, a very precisely-controllable spindle pump is fitted, which only runs within the pump body. 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

Stand-alone operation Due to its integrated pressure generation and the pure mechanical measuring principle, the model LR-Cal LDW-HK 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-HK is therefore a very precisely manufactured 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 they can be manufactured to a specific location (gravity) and also UKAS (DAkkS)-calibrated.
Easy operation The integrated dual-area spindle pump enables rapid filling of the test system and smooth pressure generation up to 1,200 bar. At the same time, the precisely adjustable spindle pump also serves for fine pressure adjustment. A control schematic for pressure generation on the instrument base facilitates quick and easy operation.

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.
Compact instrument design The LR-Cal LDW-HK is also particularly notable for its compact dimensions, which are not altered during operation since the spindle runs within the pump body. With its compact dimensions, the exceptionally robust ABS plastic housing and the low weight associated with these, the LR-Cal LDW-HK is also particularly suited to on-site applications.

The dV-2 Cool was designed for monitoring tasks at refrigerators and refrigerating plants. Vapour pressure/temperature graphs for 5 refrigerants are saved in the unit and can be selected by pressing a button.
At the touch of a button, the battery-driven instrument switches the LCD-display between vapour temperature and pressure indication, with the display offering a choice of bar / °C or PSI / °F.
The high resolution display means that dV-2 Cool can also be used for measuring leaks in vacuums.

GAS : Selection of the refrigerant.
UNITS : Switching between bar / °C and PSI / °F
CONT : The instrument turns off 15 minutes after the last key function. Activating CONT (Continuous) deactivates this automatic turn-off.
BAT LOW : The battery symbol illuminates when battery power is low.
