Description
Overview
The Gefran CSP-H melt pressure transmitter is engineered for reliable pressure measurement in high-temperature melt environments (CSP and TES). It uses an incompressible NaK hydraulic transmission to transfer process pressure to a remotely located sensing element and thick-film strain gauge technology to convert pressure into an electrical signal. The design minimises thermal signal drift and supports digital communication via HART.
