Sensor

With two decades as a trusted authority in refrigeration compressors and their critical components, ascompressors.com understands that accurate, real-time data is the foundation of efficient, reliable, and safe cooling system operation. Sensors are the eyes and ears of your refrigeration and HVAC systems, constantly monitoring vital parameters to ensure optimal performance, enable precise control, and prevent costly failures. As your dedicated supplier, we offer a comprehensive range of high-quality sensors designed for the rigorous demands of commercial and industrial cooling applications.

A sensor's primary function is to detect and measure physical quantities (like temperature, pressure, flow, humidity) and convert them into electrical signals that can be read by a controller or monitoring system. This continuous feedback loop allows for precise adjustments, proactive maintenance, and immediate fault detection, significantly extending the lifespan of your valuable compressors and ensuring consistent cooling performance.

Core Sensor Types & Key Products We Supply:

Our extensive inventory includes a variety of sensors, carefully selected for their accuracy, durability, and reliability in demanding refrigeration environments. We focus on providing solutions that offer seamless integration and robust data acquisition:

• Temperature Sensors: Absolutely critical for monitoring various points within the refrigeration cycle.

  • NTC/PTC Thermistors: Common and cost-effective, providing resistance changes with temperature. Used for evaporator coil temperature, ambient sensing, defrost termination, and cold room temperature.

  • PT100/PT1000 RTDs (Resistance Temperature Detectors): Offer higher accuracy and linearity over a wider temperature range, often used for precise control in chillers, liquid lines, or critical process cooling.

  • Thermocouples: For very high or very low temperatures, or where fast response is critical, though less common in standard refrigeration. We supply various probe types: air probes, contact probes (for pipes), and immersion probes (for liquids).

• Pressure Sensors/Transducers: Essential for monitoring refrigerant pressures at various points, crucial for compressor control and system diagnostics.

  • Analog Pressure Transducers: Output a continuous voltage or current signal proportional to pressure, enabling precise control. Used for suction pressure, discharge pressure, oil pressure, and condenser pressure.

  • Pressure Switches: Simple on/off devices that activate or deactivate at a specific pressure setpoint. Used for high-pressure cut-outs (HPCO), low-pressure cut-outs (LPCO), and fan cycling.

• Flow Sensors: Used to monitor the flow of refrigerants, water, or other fluids within the system.

  • Paddle Wheel Flow Sensors: For liquid lines to confirm circulation.

  • Thermal Mass Flow Sensors: For gas lines or precise refrigerant metering in advanced systems.

  • Differential Pressure Flow Sensors: Infer flow by measuring pressure drop across an orifice.

• Humidity Sensors: Crucial for managing environmental conditions in cold storage, chillers, and controlled atmosphere rooms to prevent condensation, mold, and product spoilage.

• Level Sensors: For monitoring refrigerant or oil levels in receivers, accumulators, or oil separators, protecting the compressor from liquid slugging or oil starvation.

• Proximity Sensors & Limit Switches: For detecting the position of valves, dampers, or movable parts in automated systems.

We ensure our sensors are built to withstand harsh conditions, offering features like robust casings, wide operating temperature ranges, high accuracy, and various output signals (e.g., 0-10V, 4-20mA, digital).
