Duct Temperature Sensors. Model TE-701 / 702

Transcription

1 Duct s Model TE-701 / 702 More than 12 types of interchangeable NTC s, precision platinum, nickel or balco s are available for universal compatibility. Five installation options probe with mounting flange or bulkhead fitting, plastic, galvanized steel, or NEMA-4 / IP- 65 steel enclosure offer the industry s most extensive range to satisfy all HVAC, appliance and industrial applications. 304 SS thin wall probe with a cold rolled hermitically sealed end forms a monolithic encapsulation cavity for the sensor and is immune to failures caused by high humidity, contamination, thermal shock and vibration. The flat probe end provides a large thermally sensitive area and the sensor is in direct thermal contact to this surface. As a result, extremely fast response is achieved to changes in temperature. Probe is attached to the enclosure or the flange using a patented process to provide a rugged, reliable and low profile attachment for ease of installation. TE-701/702 temperature sensors offer the industry s most extensive range of enclosure, installation and sensor types to satisfy all HVAC, industrial and commercial applications. These revolutionary sensors incorporate more than twenty years of product development and experience drawn from millions of installations world wide in all types of applications. This product and process design combined with automated manufacturing processes yields a rugged, reliable, repeatable and stable temperature sensor at a low cost. For large volume OEM customers, TE-701/702 temperature sensors are available in many custom configurations. Wire type, length or gage, terminals, connectors, probe lengths, enclosure options or sensor types may be customized based on volume.

2 TE-701 / 702 TE-701-A/B Flange Mount Incorporate a hermitically sealed 304 SS probe, crimped on to a 304 SS flange providing rugged assembly for duct temperature sensing. Two mounting holes are provided for #8 screws and the flange mating surface is fully gasketted to seal off the probe and screw holes. TE-701-A is available with 3 in/75mm wire leads and the TE-701-B has 6 ft/1.8 meter plenum rated cable. TE- 701-A/B is an ideal product for a rugged, reliable, quick and easy installation in air handlers, fan coil units, ducts, furnaces, freezers, ovens or any other through the wall temperature sensing application. TE-701-C/D Bulkhead mount Fast response 304 SS probe with a brass bulkhead fitting and a compression sleeve forms a strong assembly for duct temperature sensing if adjustable insertion depth is desired. The bulkhead fitting is installed in the duct, compression sleeve loosened, probe inserted to the desired length and the sleeve is tightened. Sensor is available with 3 in/75mm leads or 6 ft/1.8 meter plenum rated cable. TE-701-C/D sensors provide a low cost, rugged, quick and easy installation in air handlers, fan coil units, ducts, plenum, furnaces, freezers, ovens or any other through the wall temperature sensing application which requires adjustable insertion length. TE-702-A Polycarb Enclosure Corrosion free 30% glass filled polycarbonate enclosure designed to withstand temperature extremes, mechanical shock and vibration. 304 SS probe crimp attached to the enclosure flange for a low profile mating surface, external mounting bracket to conform to irregular surfaces, single screw cover attachment, cradle molded into the enclosure to secure the rising cage terminal block are some of the features which improve reliability and lower installation cost. TE-702-A temperature sensors provide a cost effective and reliable solution for air handlers, fan coil units, ducts, plenums, furnaces or any other application which does not require conduit wiring. 2

Failure to do so can result in damage or electrical shock. Inspect packaging for signs of damage. If damaged, notify the carrier immediately. Verify that the sensor specifications are suitable for the particular application. Installers must be trained and qualified technicians. Important: All wiring must be compatible with applicable codes, ordinances, and instructions. Location Install the sensor in a location where it will sample the average air temperature in a duct. Avoid areas where the air is stratified because these areas can cause sensing errors. Mount the TE 701 A or B Sensor Figure 3. TE 702 A Dimensions 1. Drill a 3/8-inch (9 mm) hole into the duct or plenum where the sensor will be installed. 2. Insert the sensor probe into the duct or plenum until the flange rests against the duct or plenum wall. 3. Use the flange as a template to mark and drill holes for two #8 selftapping sheet metal screws (not provided). 4. Fasten the sensor to the duct or plenum wall with the sheet metal screws. 5. Make the wiring connections. See Figure 5. IS.TE701/702-00
