Temperature Transmitter
Model HPT
The Conax Model HPT is a low cost, 2-wire, non-isolated
temperature transmitter for RTD sensors, and is designed
to fit in our popular T11 model terminal head.
The HPT housing has a removable base allowing
access to the electronics for the purpose of temperature
range changes, which are easily accomplished with
plug-in resistors.

HART® Smart Isolated 2-Wire Transmitter –
Signal Transmission the Smart Way
Model HST
The Conax Model HST HART® Smart Isolated 2-Wire Transmitter
features universal input capability in 3 variations to accept most
of today’s process parameters: Thermocouples, RTDs, DcmV,
Potentiometers, Resistance Sensors, DcmA, DCV, AC Amps,
Frequency and Pulse.

linearization for thermocouple and RTD sensor inputs, inverse
output capability, variable input signal damping, sensor
breakdown indication, full display scaling capability, auto-zero
input, and more.
Heavy duty metal case construction and carefully designed input
and output circuitry ensures a high degree of protection from
adverse environmental conditions to maximize RFI/EMI immunity.

Room Ambient Temperature Monitoring
Wall mount temperature sensors provide
highly accurate measurement of room air
temperature in industrial workspaces and
commercial, industrial or apartment
buildings. The RTD sensor is housed in an
attractive enclosure that offers very stable
readings. These units submit input to
readouts and HVAC controls, and when
combined with a data logging device, can
provide a history for validation of room
ambient temperatures. Wall mount
temperature sensors are ideal for clean
rooms, close tolerance machining centers, calibration/metrology
laboratories and medical laboratories. The assembly field-mounts onto a
standard single-gang electrical conduit box.
Model WM1 sensor is a high accuracy, encapsulated, platinum,
100Ω @ 0˚ C, ±0.3˚ C, 0.00385 Ω/Ω/˚C coefficient RTD. Increased
sensor accuracy of ±0.1˚ C is also offered.
Progressive Description Example:
Model WM2 sensor with Model HPT
fixed range transmitter offers a 4-20mA
output with an accuracy of 0.1% of
SPAN typical, supply voltage 8-38 VDC,
polarity protected. Typical room ambient
temperature range is preset at 40˚ F to

Model WM3 sensor with Model PTH-400
programmable transmitter features a
state-of-the-art microprocessor design
that enables full configuration with a
Windows®-based PC and user-friendly
software. This model offers a 4-20mA current loop output with an
accuracy of 0.1˚ C typical. Typical room ambient temperature range is
