Installation Instructions
PXMS-15K, 60K, 200K, 300K, 400K
DESCRIPTION
The PXMS-K Series pressure transmitters (e.g. PXMS-200K) are state-of-the-art instruments providing 4-20 mA output. Each Piezoresistive Pressure Transmitter contains a transducer comprised of a piezoresistive silicon chip mounted on a glass-metal feedthrough header welded into a stainless steel housing and filled with silicone oil; the very thin laser-welded stainless steel isolation-diaphragm completes the front side. Media pressure is transferred from the stainless steel isolation-diaphragm, via the oil inside the cell, to the silicon measuring chip. This construction, combined with the advanced internal signal conditioning circuitry, results in a rugged instrument with extremely small temperature error and class-leading EMI/RFI resistance.
The enclosure and all wetted parts are made of 316L stainless steel to meet NACE MR01-75.

PXMS and PXMS-K Series Pressure Transmitter Cabling Identification
The PXMS Series Pressure Transmitters have been changed. Previous pressure transmitters in this series were identified as PXMS Pressure transmitters (e.g. PXMS-200). The newest version is the
PXMS-K Series Pressure Transmitters (e.g. PXMS-200K).
IDENTIFICATION OF ELECTRICAL CABLE COLOR IS NOT INTERCHANGEABLE
BETWEEN THE TWO SERIES OF PRESSURE TRANSMITTERS.
This document contains information to assist you in identifying the pressure transmitter unit you have and the correct electrical cable colors to avoid wiring mistakes.
