Detail

Back


SPD-T
 Temperature Sensor

Features

·           temperature measurement

·          Thermistor, NI and PT sensing elements to fit your system

·          Simple and secure installation

·         Wide range of temperature probes

Applications

·          Outside air temperature measurements for summer winter compensation, energy optimization and economizer.

·         Frost protection control of outside air dampers

Temperature Sensor

The sensor measures the temperature by use of a NTC, PT, or NI-sensing element. The sensing element is either a glass packed thermistor with a negative temperature coefficient, a platinum film or a nickel thin layer based probe. Its resistance changes according to the temperature. The change follows a specified curve. Contact our sales department for curves not yet listed below.

Installation

Outside air probes must be installed on a flat vertical surface protected from direct sunlight and rain.

·          The cable gland must face downwards.

·          To install the sensor, remove cover

·          Place seal and washer below the long mounting screw. Securely fix it to wall.

·          Thread wires through cable gland or conduit connector

·          Connect the wires according to the wiring diagram to the measuring circuit in the cover:

o    The Thermistors require two conductors; normally 18ga unshielded twisted pair.

o    The PT1000 sensors come with each two terminal connectors in order to connect up to four conductors for compensating conductor resistance.

·          Tighten cable gland

·          Assemble the cover with the base plate. Make sure the seal in the seal grove of the cover is not damaged and in place.

·          Tighten the four screws of the cover with moderate torque to complete the installation.
