TSP-5022

Actuator: Proportional with Airflow Trans, 50 in-lbs, 60 degress/min


These combination air flow transducers and actuator units are designed primarily for variable air volume terminal units controlled via Direct Digital Control (DDC) systems such as KMC’s Digital System. They can be used in slave or dual duct tracking applications. Air flow is sensed by utilizing a single or multi-point differential (velocity) pressure measuring station or pitot tube. Air flow sensing is accomplished utilizing twin platinum resistance temperature detectors. Velocity measurement is maintained at 3% accuracy over the range of 0 to 3,300 feet per minute (FPM). Each unit mounts directly to a 1/2" diameter or 3/8" square damper shaft, or a 3/8" diameter shaft (HFO-0011 shaft adaptor required). Damper control is provided by an 18°/minute or 60°/minute actuator. The actuator is controlled by an SPDT “floating” input (on the TSP-5003/5023) or 2 to 10 VDC proportional input (on the TSP-5002/5022). A minimum of 50 in-lbs. torque is provided. Both minimum and maximum stops are standard to limit the rotation. A gear disengagement feature allows positioning the damper and/or gear-train without energizing the actuator. A 10,000 ohm, 1/3 watt feedback potentiometer is standard on the TSP-5003/5023 (only).
