Whether it is the pressure of the hydraulic measurement control circuit that provides feedback for the pump pressure of the HVAC system, or the pressure of the coolant flow, the heavy-load sensor can output a high-level signal. Currently, design engineers are faced with the huge challenge of designing more complex control systems. These systems rely on providing more feedback signals than previous systems. Therefore, design engineers must consider components that meet the requirements of high accuracy, lower overall cost, and ease of implementation. Current control systems mostly use pressure switches to control. This switch opens and closes around a set point, and its output is usually reviewed at the end of the day. Such systems are mainly used for monitoring. Compared with the above-mentioned control system, the system using the pressure sensor can measure the pressure spike in time and accurately, so as to issue a warning before the danger occurs or the control system fails. The sensor connected to the computer can measure the actual pressure, so that the user can accurately monitor and control the system. Pressure data is generally used to dynamically measure system performance, monitor usage status, and ensure system energy efficiency. Sensor-based systems can provide more and more effective data points.
In short, the heavy-duty pressure sensor is a pressure measuring device with a housing, a metal pressure interface, and a high-level signal output. Many sensors are equipped with a round metal or plastic housing, which is cylindrical in appearance, with a pressure port on one end and a cable or connector on the other end. This type of heavy-duty pressure sensor is often used in extreme temperatures and electromagnetic interference environments. Customers in the industrial and transportation sectors use pressure sensors in control systems to achieve pressure measurement and monitoring of fluids such as coolant or lubricants. At the same time, it can also detect pressure spike feedback in time, find problems such as system blockages, and find solutions immediately.
The control system is becoming more and more intelligent and complex, and the sensor technology must also keep developing synchronously to adapt to the application requirements. Gone are the days of sensors that require signal conditioning and calibration. From sensor design, implementation to application, you no longer need to worry about sensor functional issues. In view of the fact that the sensor is a very important pressure measurement device, and there are many types of sensors on the market, and the quality is uneven, you must choose carefully.
Possibilities overview
Before listing the sensor purchase list, it is important to review the various application scenarios. Need to consider what are the alternatives and how to meet the requirements and specifications of their own design. As mentioned earlier, control and monitoring systems have undergone tremendous changes in the past few decades, mainly due to increased design complexity. These changes include manual systems becoming control systems based on electronic technology, multi-components becoming highly integrated products, and greater focus on cost issues. There are multiple solutions for heavy-duty applications, what are the heavy-duty environments? Here are just some specific examples, such as an environment with a large temperature range (such as -40 ° C to 125 ° C [-40 ° F to 257 ° F]), there are refrigerants, engine oil, brake fluid, hydraulic oil Harsh media and environments using compressed air. Although the above temperature ranges and harsh environments may not be the most extreme environments, they represent the majority of transportation and industrial environment applications.
Heavy-duty pressure sensors can be used in the following areas:
Used in HVAC / refrigeration and air conditioning applications, to monitor system performance, and to control compressor inlet and outlet pressures, roof chillers, refrigeration rooms, refrigerant recovery systems, and compressor oil pressure. Used in air compressors to monitor compressor performance and efficiency, including monitoring compressor inlet and outlet pressure, filter pressure drop, cooling water inlet and outlet pressure, and compressor oil pressure. Used for transportation applications, to maintain the pressure, hydraulic power, flow and liquid level of key systems such as pneumatic, light hydraulic, brake pressure, oil pressure, transmission, and truck / trailer airlocks to maintain heavy-duty equipment performance. There are many types of sensors on the market, and the quality is uneven, so you must carefully study the alternative products. Specifically, the product should be analyzed in terms of reliability, calibration, zero compensation, sensitivity, and total error range.
