Mamac Systems TE-704 Pipe Temperature Sensor

TE-704 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-704:

  • Four immersion thermowell installation options—brass adapter with 304 SS probe for adjustable insertion, plastic, galvanized steel or NEMA-4/IP-65 steel enclosure. Four strap on surface mount installation options—rugged 304 SS hermetically sealed probe, plastic, galvanized steel or NEMA-4/IP-65 contact surface temperature sensors 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 encapsulated cavity for the sensor and is immune to failures caused by high humidity, contamination, thermal shock and vibration.
  • Fast response brass contact sensor for strap on applications is insulated from the enclosure to provide accurate pipe surface temperature measurement.
  • More than 16 types of interchangeable NTC thermistors, precision platinum, nickel or balco RTDs are available for universal compatibility.
