TSP-5023

Actuator: Tri-State 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 €œfloating€ 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).
