Differential pressure transmitter

Relative and diﬀerential
pressure transmitter
Type 402
Type 402 pressure transmitters are ideally suited to measuring
fine air flow in air conditioning systems, and fine pressures in theenvironmental / medical technology sectors.
Individually ranged sensors ensure optimum accuracy and longterm stability of measurement. Location is quick and easy, either
via a mounting plate or directly onto a PCB.

Pressure range
0 ... 3 – 50 mbar

+ Attractive price / performance ratio+ Excellent synergy of diaphragm technology and ceramicelements+ Special adapter for top-hat rail mounting+ Direct pcb mounting with simple snap-on system
