Edge & Function


*Gauge pressure sensor is a capacitance type whose diaphragm is high corrosion resistant and capable of quick response

*Micro differential pressure sensor is an indductance type, which can withstand the pressure 10 times as high as its full scale

*Various measuring ranges available

*Built-in accurate sensor

*Analog output

*DM-3501B comes with upper/lower limit settings


*BCD output: Open collector or TTL type are avaialble

*Analog output: 10V max

*DSP terminal: External voltage display

*External sensor configuration
Standard cable length 3m Accuracy of Spalash-proof sensor (PT-141) is ±0.25% of F.S.

*Panel mount model can be selected from gauge pressure, micro pressure, Positive/Negative pressure

*High corrosion resistance sensor made of SUS316 (for limited ranges)
