Temperature Transmitter Head Mounted Advantages General Description
Two wire 4~20mA current output signal
RTD and thermocouple inputs
Measuring ranges from -50 to 400°C /
-100 to 1500°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 low level
mV/thermocouple/RTD signals to carry to a
long distance or guard against heavy field
electrical noise. The transmitter converts
RTD and thermocouple 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. T15X series temperature transmitters are designed to fit
into standard weather or explosion-proofed terminal
heads used on RTD or thermocouple 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.
T15X 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. Measuring ranges PT100 ohm, JIS-C-1604-1981
