Conductivity-Resistivity Transmitter The Signet 8850 Conductivity/Resistivity Transmitter is designed for broad application and ease of setup and use. Full-microprocessor based electronics allow wide operating range, and long term signal stability due in three different instrument versions: the 8850-1 for traditional two-wire current loop, the 8850-2 features current loop plus two dry contact relays, or the 8850-3 with two-wire current loop, one sensor input signal and two current loop outputs. The 8850 is offered with a NEMA 4X/IP65 front panel with a self-healing window in a convenient 1/4 DIN package for easy mounting. The 8850 can be configured via a simole menu system. In addition to programmable outputs and relays, the unit can also be set up to measure raw conductivity values.
