PSM-AB
Miniature Pressure Sensor

Summary

The PSM-AB is a miniature pressure sensor with a flurocarbon resin cable. It adopts quarter-bridge 3-wire mode and configures a full bridge by a bridge adapter.
Rated Capacity: 100, 200 kPa
Compensated Temperature: 0 to 50ºC

Features

• Bridge adapters are standard provided
• Installed by adhesives
• Pressure measurement of denser points than conventional models is possible.

PSM-1KAB
100 kPa

Specifications

Performance
Rated Capacity 100 kPa
Nonlinearity Within ±1% RO
Hysteresis Within ±1% RO
Rated Output 0.275 mV/V ±25%
Note: Rated output is sorted to one of the classes divided by every 0.007 mV/V difference in output value. Since the rated output stated in the Test Data Sheet is the center value of the class, it may have a maximum error of ±0.0035 mV/V.

To Ensure Safe Usage

(Note 1) Copper alloy is used for sensing element. Avoid measuring corrosive liquid or gas.
(Note 2) The mainframe has been assembled using an epoxy adhesive. Do not therefore use the transducer to measure organic solvent. (e.g. Toluene, ketone and others)
