Applicatios
These are recommended in applications
requiring amplification of RTD signals to
carry to a long distance or guard against
heavy field electrical noise. The transmitter
converts RTD inputs to an analong singal
for direct interface with indicators, recorders,
controllers, PLC, DCS systems can be used
for a wide range of applications in process
control, automatic machinery and hydraulic
or pneumatic system design.

T900 series temperature transmitters are designed to fit
into standard molded terminal heads used on RTD
assemblies to provide a 4~20mA transmission signal. It
is a cost effective solution for all temperature measurement
ａnd accurate, durable and reliable.
Numerous configurations for measurement in many
defferent mediums are offered. Generally the transmitter
produces a linear 4~20mA output carried on a two-wire
system. The transmitter is supplied factory calibrated,
but also has zero and span potentiometers for field
adjustment or calibration.
