GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM

ALL PURPOSE TEMPERATURE TRANSMITTER WITH LCD

TDAP SERIES

PRODUCT DESCRIPTION

The TDAP series 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. The

transmitter provides a high accuracy signal with

excellent long term stability, low hysteresis and fast

response. It is available with various scaled ranges.

A hinged and gasketed Polycarbonate enclosure is

included, and an LCD is provided in either °C or °F.

TYPICAL INSTALLATION

For complete installation and wiring details,

please refer to the product installation

instructions.

The duct type probes are installed through a hole

in the side of the duct to monitor a single point

temperature within the duct. Since the probes are tip

sensitive, select a probe length that places the sensor

well into the duct. Install the probe in a straight

section of duct at a suitable distance downstream

from any heating, cooling or humidification devices.

The enclosure provides mounting tabs for ease of

installation.

NOTE: For immersion applications, a T2 series

thermowell is required. When using a T1 series

thermowell an adapter will be required.
