Air Duct Temperate Sensor Features    

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

·          Simple and secure installation

·          Wide range of temperature probes

·          Compact size and modern design

Applications

·          On return air ducts to measure heating/cooling return air

·          On supply air ducts to measure heating/cooling supply air

·          In heat exchangers and air handling units to control heating/cooling coils for temperature and humidity control

·          As frost protection sensor

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 or a platinum film sensor or a thin nickel layer on a ceramic substrate. Its resistance changes according to the temperature. The change follows a specified curve. Below is a list of available sensor elements, curves and accuracies:

Ordering

Ordering number:TS-XX-D-YY

XX indicates the sensor element optional,see table above.

YY indicates the probe length. Standard probe length is 20 cm.

For example:TS-N10-D-20

-N10 indicates the sensor element is Thermistor 10k .

-20     indicates the probe length is 20 cm.

Duct probes should be installed directly on the duct, in an area where the air stream is well mixed:

·          Locate a supply air sensor two or three meters down stream from the nearest fan and coil.

·          Mount the return air sensor close to the air inlet but downstream from a return fan if one is present.

·          To install the sensor, assemble base plate and probe, then drill a 8 mm hole and two 3 mm holes on a diameter of 25 mm in the duct.

·          Use two self-tapping sheet metal screws to tighten the mounting circuit in the cover.

·          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 PT100, PT1000 and NI1000 sensors come with each two terminal connectors in order to connect up to four conductors for compensating conductor resistance.

·          Assemble the cover with the mounting plate.

·          Insert the assembled probe through the center opening of the mounting plate into the air stream.

·          Tighten the horizontal screw on the mounting plate to fix the probe to the duct.
