GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM

OUTSIDE TEMPERATURE TRANSMITTER

TXOS SERIES

PRODUCT DESCRIPTION

The single point outside temperature transmitter

utilizes a precision platinum RTD sensor. All probes

are constructed to provide excellent heat transfer,

fast response and are potted to resist moisture

penetration. It is provided in a weatherproof

Polycarbonate enclosure. 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 outside temperature transmitter should be

mounted on an outside north facing wall, under

the eaves which will provide protection from direct

sunlight.

The outside temperature sensor can be mounted

directly to building’s wall face using the provided

mounting holes. There is one 0.85” hole for conduit

connection.

NOTE: This product is factory calibrated and any field adjustment will void the warranty.
