PTL

The PTL Pneumatic Temperature Controller operates over a wider temperature range than our standard “T” temperature pilot. These temperature controllers also react quicker to temperature change which make them an excellent choice for instantaneous hot water applications. The PTL controller is designed to be directly mounted to a process tank or vessel.

The PTL Pneumatic Temperature Controller is used in conjunction with an “A” Air Pilot to control the operation of the HD Regulator. The PTL uses a bimetallic element to sense temperature. The air supply is connected to the inlet of the controller and the air output signal is fed directly to an Air Pilot, which controls the opening and closing of the steam regulating valve.

PTR

The PTR Pneumatic Temperature Controller operates over a wider temperature range than our standard “T” temperature pilot. These temperature controllers also react quicker to temperature change which make them an excellent choice for instantaneous hot water applications. The PTR controller is designed to be remotely mounted to a control panel; the sensor mounts directly to the process tank and connects to the controller with a capillary.

The PTR Pneumatic Temperature Controller is used in conjunction with an “A” Air Pilot to control the operation of the HD Regulator.The PTR uses a hydraulically filled bulb with a 4-ft. capillary to sense temperature. The air supply is connected to the inlet of the controller and the air output signal is fed directly to an Air Pilot, which controls the opening and closing of the steam regulating valve.
