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

Ordering number:TS-XX-R

XX indicates the sensor element optional,see table above.

For example:TS-N10-R

-N10 indicates the sensor element is Thermistor 10k .

Construction

This sensor is constructed to high quality standards. The housing is available in different colors with RAL9003 as the standard. It is made of fire proof ABS plastic and the unobtrusive design and size will blend into any interior decoration. A metal mounting plate that fits on most commercially available recessed conduit boxes guarantees a save installation.

Installation

· When installing the unit, fix the base plate first, connect the electrical connections then hook on the cover and secure it.

· The end of the conduit at the sensor must be sealed to prevent false measurements due to draughts through the conduit.

· 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.
