Local Display With Temperature Transmitter T758, T759
Advantages General Description
Two wire 4~20mA current output signal
RTD inputs
Measuring ranges from -50 to 400°C
Loop powered 4~20mA with LED local
display
Explosion protection Ex d IIC T6
Excellent accuracy and long term
stability
Applications
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 analog signal for direct interface with
indicators, recorders, controllers, PLC, DCS
systems can be used for a wide range
ofapplications in process control, automatic
machinery and hydraulic or pneumatic
system design.

T75X series temperature transmitters are designed to fit
into standard weather or explosion-proofed 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 different mediums are offered.
Generally the transmitter produces a linear 4~20mA
output carried on a two-wire system and optional voltage
range of 1~5V DC can also be available. The transmitter
is supplied factory calibrated, but also has zero and span
potentiometers for field adjustment or calibration.
T75X provides a loop powered 4~20mA/2-wire with LED
local display and in the harzadous environment,
explosion protected terminal head can be also available.
