Spence Engineering T6150250 Temp Control

The Spence Engineering T6150250, identical to the industry-standard T61 Series, is a high-performance pneumatic temperature controller designed for precise steam pressure regulation and process fluid heating. Built with a rugged bronze body, this pilot-operated controller features a 50-250°F temperature range, making it ideal for HVAC mechanical rooms and industrial heat exchangers. It functions by modulating the control pressure to a pneumatic temperature pilot, ensuring stable discharge temperatures even under fluctuating load conditions. This unit is frequently used in constant pressure pilot configurations to provide accurate proportional control. The heavy-duty construction minimizes maintenance requirements in high-demand steam systems. By utilizing a thermal bulb sensing element and capillary system, the T6150250 provides rapid response times to temperature deviations, maintaining system efficiency and protecting downstream equipment from thermal stress. This pneumatic controller is a reliable drop-in replacement for existing T61 installations requiring a wide temperature setpoint range.

Common Questions Regarding the T6150250

How do I calibrate the T6150250 for specific steam applications?
Calibration is achieved by adjusting the spring tension on the pilot to match the required temperature setpoint. Ensure the thermal bulb is fully submerged in the medium being sensed for accurate feedback.

Can this pilot be used with different Spence main valves?
Yes, the T61 pneumatic pilot is designed to work in conjunction with Spence Type E or Type C main valves to regulate steam flow based on temperature demand.

What air pressure is required for the pneumatic signal?
Typically, these controllers operate on a standard 3-15 psi or 0-30 psi pneumatic signal, depending on the specific control valve and actuator configuration.
