Johnson Controls A99BB-25 Temperature Sensor The 9-13 psi range is

The 9-13 psi range is typically used in applications where the valve needs to remain closed or open against specific system pressures when the control signal is at its midpoint or limit

The Robertshaw 620-202 is rated for continuous operation

Higher dielectric protection: Rated for 440 VAC

Synthetic Fiber Reinforcement: Minimizes "creep" and the need for frequent re-tensioning after the initial run-in period

ensuring compatibility with models 3508

Johnson Controls A99BB-25 Temperature Sensor The 9-13 psi range isThe Johnson Controls A99BB 25 Temperature Sensor is a high accuracy PTC silicon sensor designed for precision monitoring in commercial refrigeration and HVAC applications. This passive Positive Temperature Coefficient sensing element provides a reference resistance of 1,035 ohms at 77? F (25? C), ensuring reliable data for system 450 controls, A419, and A421 series modules. The sensor is constructed with a stainless steel bulb and a 9 3 4 inch PVC
