Sensors portfolio
TT-D-A Duct Sensors (Passive Output, 10K3A1)
The TT-D-A direct output, temperature sensor used to measure air temperature in ducts. Units contain either a high quality thermistor, nickel or platinum sensing element. The sensing element is fitted into a stainless steel probe. A flange plate is available for adjustment of penetration depth (order as TT-DFP).
TT-O-A Outside Air Sensors (Passive Output, 10K3A1)
The TT-O-A range are direct output, temperature sensors for measuring outside air temperature. Units contain either a high quality thermistor, Nickel or Platinum sensing element. The sensors are housed in IP65 rated enclosures. The TT-O-A has a cap containing the sensing element located externally in the shadow of the lid to curb the effects of solar gain, but should always be situated in a sheltered position on a north facing wall.
TT-I-A Immersion Sensors 150 mm (Passive Output, 10K3A1)
These immersion sensors are used for measuring the temperature of liquids in pipework. Units contain either a high quality thermistor, nickel or platinum element. The TT-I-A sensing element is housed in a stainless steel probe fitted to an IP65 rated enclosure, for direct mounting into TT-PO521 or TT-PO-HP range of stainless steel pockets.
TT-C-A Strap-on Temperature Sensors (Passive Output, 10K3A1)
The TT-C-A is used to measure pipe temperature, and contain either a high quality thermistor, nickel or platinum element, which is housed in a 50mm (1.97") long probe with two metres (6.56 ft) of PTFE 2-core cable as standard connecting the probe to an IP65 housing for termination.
TT-PO Immersion Sensor Pockets
TT-PO521 and TT-PO-HP range of stainless steel pockets are for use with immersion sensors TT-I-A . The two part welded TT-PO521 pockets are intended for low flow applications. They may be used in applications such as sumps or storage tanks or low flowing water in pipes. For applications requiring installation in high flowing water, the TT-PO-HP should be used. Pockets are designed to accept either a 65mm (2.56”), 150mm (5.91”) or 250mm (9.84”) x 6mm (0.24”) dia. probes, which are locked in position by a grub screw.
TT-S-A Temp sensor (Passive Output, 10K3A1)
This range of innovative space sensors is designed to meet the exacting standards of today’s architects, specifiers and building owners. Its unique low profile, curved style allows it to blend seamlessly in to the architecture of modern and older buildings alike. As with its predecessor the TT-S-A range can be supplied with a wide range of user interface options such as set-point adjustment, fan speed and momentary switches etc. to give the customer additional functionality. Sontay also offers a complete range of customised user interfaces for every requirement.
TT-555-A Flying Lead Sensors (Passive Output, 10K3A1)
The TT-555 is a direct output temperature Sensor used to measure air temperature, especially in fan-coil units etc, and contain either a high quality thermistor, nickel or platinum sensing element. The standard cable length is two metres (6.56 ft) of 2-core screened cable. Longer lengths can be made to order.
