The Series 642 Pressure Transmitter uses high end ASIC technology to compensate for both linearity and thermal errors, providing an output with an accuracy of 0.1% of F.S. The 642 is therefore well suited for applications where precision measurement and control is an absolute must. Units are constructed of 316 and 316 LSS wetted parts for superior compatibility. Zero and span are independently adjustable. Transmitters feature simple two wire operation plus reverse polarity protection. Liquid fill provides shock and vibration resistant protection.

APPLICATIONS
Aerospace industries, factory automation, equipment monitoring and industrial research. The Series 642 Pressure Transmitter is ideal for use in harsh environments.
