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:
Item name | Sensing element | Curve | Compatible with |
N18 | Thermistor 1.8k at 25 °C | Curve 5 | TAC, CSI |
N3 | Thermistor 3k at 25 °C | Curve 6 | Alerton |
N10 | Thermistor 10k at 25 °C | Curve 24 | Hysine, Alerton,ALC, Delta,Trane, CSI |
N11 | Thermistor 10k at 25 °C | Curve 7 | Andover, Invensys, Carrier, KMC |
N20 | Thermistor 20k at 25 °C | Curve 20 | Honeywell |
N100 | Thermistor 100k at 25 °C | Curve 9 | Siemens SBT |
Tp1 | PT100 | 0.3851ohm/K | Honeywell |
Tp2 | PT1000 | 3.851ohm/K | Johnson Control |
TK5 | NI1000 | 5000ppm/k | Siemens SBT |
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.
