DSA Speed Sensor DSA2S18K0250D/12P DSA2S18K1500D/12P for Industrial
Refrigeration & Motor Control Systems
Product Description
The DSA Series Speed Sensors (DSA2S18K0250D/12P and DSA2S18K1500D/12P) are high-performance industrial sensors designed for precise rotational speed measurement in compressors, motors, and refrigeration equipment. Built with high-quality stainless steel housing and advanced Hall-effect
technology, these sensors ensure accurate pulse output, excellent
anti-interference capability, and consistent performance in harsh
operating environments.
These sensors are commonly used in Carrier, Thermo King, Bitzer, and industrial refrigeration units, providing real-time speed feedback for compressor protection,
load regulation, and energy optimization. Their high sensitivity and robust construction make them ideal for continuous use in transport refrigeration,
cold storage systems, and HVAC applications.
