The pressure transmitter with silicon sensor is used to detect the differential pressure (0 to 0.4 bar – 0 to 16 bar) in liquid, gaseous, and low-aggressive media.
The differential pressure measuring cell records two pressures. The differential value from these two pressures is converted into an analog two-wire current signal or ratiometric output signal. The piezoresistive silicon sensor is integrated into a stainless steel measuring cell. A plastic case accommodates the stainless steel measuring cell and the electronics.
Type 401050 is the differential pressure model in the JUMO MIDAS pressure transmitter range with sensor technology that has been proven thousands of times over. An almost fully automated production sequence (digital compensation and calibration of the sensor module) and a functional design reduce both the production time and manufacturing costs.
- Process reliability
The high quality of every pressure transmitter is ensured by the full final inspection within the fully automatic measuring and calibration facility.
High-quality materials allow for a wide application field. Various output signals, different process connections, and case materials are available.
- Filter monitoring
A typical application is filter monitoring in gases or liquids, which uses the different pressure ratios before and after the filter to ascertain its pollution.
- Filling level
In pressurized boilers, a differential pressure measurement can be used to determine the exact filling level, irrespective of system pressure fluctuations.
- Pump control
The rotational speed of a pump can be adapted to the requirements of capacity and energy consumption via a control system by measuring the pressure ratio before and after the pump.
