Mamac Systems TE-701 Duct Temperature Sensor

TE 701 temperature sensors offer the industry's most extensive range of enclosure, installation and sensor types to satisfy all HVAC, industrial and commercial applications.

Features of Mamac Systems TE-701:

  • 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 hermetically 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.
  • More than 16 types of interchangeable NTC thermistors, precision platinum, nickel or balco RTDs are available for universal compatibility.
