GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM

RIGID DUCT AVERAGE TEMPERATURE TRANSMITTER

TXDR SERIES

CABLE GLAND FITTING

THREAD ADAPTER 1/2” NPT TO M16

ACCESSORIES - INCLUDED WITH E ENCLOSURE OPTION

PRODUCT DESCRIPTION

The multi-point rigid duct average temperature

transmitter incorporates numerous precision

platinum RTD’s at equal distances, encapsulated

in a 6.00mm (0.236”) OD, 304 series 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 is

available with various ranges.

TYPICAL INSTALLATION

For complete installation and wiring details,

please refer to the product installation

instructions.

The rigid duct average type probes are installed

in the side of the duct to monitor the average

temperature within the duct. Select a probe length

that allows the probe to span the duct width. 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: This product is factory calibrated and any field adjustment will void the warranty.
