Notes: (1) Thermocouple models output proportional to mV output of thermocouple.
Not linearized to temperature. (2) Non-Isolated unit for use with ungrounded probes.

Code table below). Adjustability of
±25% for zero and span is provided
to facilitate some rangeability.
The transmitted signal eliminates
noise pickup, voltage drops, multiple
cold junction errors and requires
only a twisted pair of copper wire
for loop connections. TX93, TX94
and TX95 are ultra-low profile
transmitters at an economical price.
