Features Five installation options — probe with mounting flange or bulkhead fitting and plastic, galvanized steel, or NEMA-4/IP-65 enclosure — offer the industry's most extensive range to satisfy all HVAC, appliance and industrial applications 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 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 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 15 types of interchangeable NTC thermistors, precision platinum, nickel or Balco RTDs are available for universal compatibility
