Description

Pressure and differential pressure measuring transducer / switch PREMASREG® 114x
Quality product for the HVAC sector, accuracy ±1.5%

The electronic PREMASREG® 1141 pressure sensor device and switch supports eight switchable measuring ranges (eight devices in one) and features one switching output, one continuous output and a display for setting the switchpoint and showing the actual pressure. It serves as a differential pressure switch/monitor and continuous pressure sensor transmitter in a single unit.
The pressure sensor device is used for above-atmospheric, below-atmospheric or differential pressure measurement in clean air, including limit value switching. The piezoresistive measuring element guarantees a high level of reliability and accuracy. Applications are found in cleanroom, medical and filter engineering, in ventilation and air conditioning ducts, in spray booths and large-scale catering facilities, in filters monitoring and level measurement or frequency converter triggering. Media measured by the pressure measuring transducer are air (non-precipitating) or gaseous, non-aggressive, non-combustible media. The pressure sensor device has a manual zero-point pushbutton and an offset potentiometer for correction of the final value and the switching point. Fine adjustment by the user is possible at any time. Our ASD-06 connection set (6.5 ft connection hose, two pressure connection nipples, screws) is included in the scope of supply.
