Category: Signal isolator
Views: 239
Applications: Intelligent Temperature Transmitter utilized in automated control systems is a kind of instrument for transformation & distribution, isolation, transmission, operation of a variety of industrial signal, it can also be used with all kinds of industrial sensor to retrieve parameters of signals, isolation, transformation and transmission for remote monitoring local data collection.

SPE-7100 Series temperature signal  isolate

Temperature Transmitter isolate the resistance temperature detector (RTD) or thermocouple (TC) signals on-site, amplify them, and convert them into temperature linear DC signals, and export to the control system, and when used as a TC temperature transmitter, it has automatic cold junction temperature compensation function. It can change parameters with a supporting PC software. It can be used together with modular instrumentation and DCS, PLC and other systems, to offer signal isolation, signal conversion, signal distribution, signal processing and other functions to field instrument, thereby enhancing the immunity of automatic control system in the industrial production process, and ensuring system stability and reliability. This product has many varieties, such as 1 in/1 out, 1 in/2 out, 2 in/2 out, with input/output magnetic isolation.
