A99B Temperature Sensors
A99B Series Temperature Sensor
Description
The A99B Series Temperature Sensors are
passive PTC (Positive Temperature
Coefficient) sensors. The A99B sensors are
splashproof and are designed to measure
temperature in a variety of refrigeration
applications. Several accessories allow easy
tailoring of the temperature sensor to various
mounting configurations.
Applications include temperature sensing for
freezers and coolers, as well as in defrost
termination sensing, space and return air
temperature sensing, and condenser fan
cycling.
Refer to the A99B Series Temperature
Sensors Product Bulletin (LIT-125186) for
important product application information.
Features
• variety of lead lengths available to
encompass most application requirements
and simplify wiring sensors
• an assortment of mounting hardware
provides configurations for many
applications
• exceptional accuracy of sensing element
provides excellent performance in a wide
variety of control applications
• stainless steel sensing bulb allows use in
more applications than other types of bulbs
without corrosion
• lead length may be extended up to
800 ft (244 m)
Applications
The A99B temperature sensor line offers an economical solution for a
wide variety of temperature sensing needs in refrigeration and HVAC
applications.
Typical temperature sensing applications and environments include:
• freezers
• display cases
• walk-in coolers
