Temperature Sensors

A99B Series: Temperature Sensors

Description

The A99B sensor incorporates a PTC silicon-sensing element whose resistance increases with an increase in temperature. The sensor will exhibit a 0.42%/°F resistive change and has a reference resistance of 1035 ohms at 77°F (25°C).

 

Features

  • Variety of lead lengths encompasses most application requirements and simplifies wiring sensors.
  • Assortment of mounting hardware available provides configuration for many applications—customizable.
  • Very accurate sensing element provides excellent performance in a wide variety of control applications.
  • Stainless steel sensor bulb allows use in more applications than other types of bulbs; no corrosion.

 

Applications

  • Sensing for freezers and coolers
  • Defrost termination sensing
  • Space and return air temperature sensing
  • Condenser fan cycling
