GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM

REMOTE PROBE STRAP-ON TEMPERATURE TRANSMITTER WITH LCD

TDRP SERIES

PRODUCT DESCRIPTION

The single point strap-on temperature

transmitter incorporates a precision platinum

RTD encapsulated in a 6 mm (0.236”) OD, 304

stainless steel probe and is available in various

lengths. All probes provide excellent heat transfer,

fast response and resist moisture penetration.

A transmitter that provides a high accuracy

signal with excellent long term stability, low

hysteresis and fast response for measurement

of pipe temperatures. A hinged and gasketed

Polycarbonate enclosure is included for ease of

installation. An LCD is provided in either °C or °F.

TYPICAL INSTALLATION

For complete installation and wiring details,

please refer to the product installation

instructions.

Find a suitable location along the pipe where both

the probe and remote enclosure can be mounted.

If necessary, remove a section of insulation from

the pipe. Position the probe directly on the pipe

and secure using a pipe clamp. For added security,

make 1 to 3 loops of the sensor cable around the

pipe and feed through wire hole on the enclosure

and secure using the supplied grommet. If

applicable, the pipe insulation can be re-applied

to the pipe over the probe.
