Seametrics’ Submersible Pressure Transducer PS98i

4-20 mA PS98i Measures Pressure, Level, Optional Temperature


Gauge: PSI 1, 5, 15, 30, 50, 100, 300

Absolute²: PSI 30, 50, 100, 300

The PS98i Offers great noise immunity and transient protection, this industry standard 4-20 mA pressure transmitter is both rugged and accurate. Made from 316 stainless steel, fluoropolymer, and PTFE, it provides a secure housing and reliable readings.

The PS98i can be easily configured to SCADA, PLC, Data Loggers, and Displays.

Designed to resist data interference, the PS98i is the smart choice for almost any site where you need to measure pressure/level or temperature.

This sensor also includes added thermal compensation to offer pinpoint accuracy, typically within 0.06% FSO, making it ideal for sites where reliable readings are a must.
