GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM

GLASS TEMPERATURE TRANSMITTER WITH LCD

TDGL SERIES

CABLE GLAND FITTING

THREAD ADAPTER 1/2” NPT TO M16

ACCESSORIES - INCLUDED WITH F ENCLOSURE OPTION

PRODUCT DESCRIPTION

The single point glass temperature sensor utilizes

a precision sensor encapsulated in a 31.75mm L

x 9.525mm W x 9.525 mm H (1.25” x .375” x .375”)

Aluminum probe. Standard wire length is 1.5 m

(5’). The probe is constructed to provide excellent

heat transfer, fast response and is potted to resist

moisture penetration. The transmitter provides

a high accuracy signal with excellent long term

stability, low hysteresis and fast response and is

available with various ranges. 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 on an exterior window

where both the probe and enclosure can be

mounted. On one side apply epoxy compound and

press firmly against the glass. Hold in place until the

epoxy has set.

Enclosure provides mounting tabs for ease of

installation.
