What is a hydraulic pressure transducer?

A hydraulic pressure sensor is a sensor used to measure pressure in a hydraulic system. It can monitor and control the pressure of the hydraulic system by converting the pressure into electrical signals. to ensure the pressure within the system is at the correct level, or to allow the controller to increase or decrease pressure.

Hydraulic Pressure Transducers are used in a variety of hydraulic systems such as power steering systems, shock absorbers, braking systems, utility vehicles such as excavators and aerial work platforms, lifts and industrial machinery such as hydraulic presses.

hydraulic pressure transducer Applications

Hydraulic pressure transducer is a device that converts hydraulic signals into electrical signals and is widely used in a variety of hydraulic systems and industrial processes. The following are several main applications of hydraulic pressure sensors: booster cylinders, superchargers, gas-liquid booster cylinders, gas-liquid boosters, presses, compressors, air conditioning and refrigeration equipment and other fields.

  1. Hydraulic system monitoring and control: Hydraulic pressure sensors can be used to monitor the working pressure in the hydraulic system to ensure its normal operation. When the pressure reaches or exceeds the set upper or lower limit, the alarm or control system can respond. Such as adjusting the output of the pump, opening or closing valves, etc.
  2. Aerospace applications: In the hydraulic systems of aircraft and spacecraft, pressure sensors are used to ensure the normal operation of the system. Monitor the pressure status of the aircraft landing gear, brakes and flight control systems.
  3. Automobile industry: In the hydraulic brake system, power steering system and suspension system of automobiles, pressure sensors may be used to ensure the normal operation and safety of the system.
  4. Industrial automation and manufacturing: In production lines, injection molding machines, pressure forming machines and other equipment, hydraulic pressure sensors are used to monitor and control the process to ensure product quality.
  5. Medical Equipment: In some medical equipment, such as cardiac assist equipment, hydraulic pressure sensors are used to monitor and control the flow and pressure of hydraulic fluid.
  6. Energy and power industry: In power stations and renewable energy equipment, hydraulic pressure sensors can be used to monitor the pressure of liquid media (such as hydraulic oil) to ensure normal operation of the equipment.

Hydraulic Pressure Transducers Installation

The installation location of the hydraulic pressure sensor should be determined based on the actual conditions of the hydraulic system. Generally speaking, the sensor should be installed at the most important position in the hydraulic system to monitor the highest pressure of the hydraulic system.

Common installation locations include the following:

  1. Pump outlet: Installed at the pump outlet, the output pressure of the pump can be monitored to ensure the normal operation of the pump.
  2. The inlet of the oil cylinder: Installed at the inlet of the oil cylinder, the pressure of the oil cylinder can be monitored to ensure the normal operation of the oil cylinder.
  3. The outlet of the oil cylinder: Installed at the outlet of the oil cylinder, the output pressure of the oil cylinder can be monitored to ensure the normal operation of the oil cylinder.
  4. High-pressure side of the oil line: Installed on the high-pressure side of the oil line, the highest pressure of the entire hydraulic system can be monitored to ensure the normal operation of the hydraulic system.

FAQ

The function of the pressure sensor is to convert the pressure signal into an electrical signal. It usually consists of sensitive components and conversion components. When subjected to pressure, the sensitive element will produce physical or chemical changes, and then this change will be converted into an electrical signal output through the conversion element.

The 4-20mA pressure transducer is a pressure sensor that outputs a 4-20mA current signal. The 4-20mA signal is a standard signal in industrial automation. It has good anti-interference and can be transmitted over long distances. In this type of sensor, 4mA usually represents the lowest pressure value, while 20mA represents the maximum pressure value.

The three common pressure transmitters are:

  • Strain gauge pressure sensor: This sensor detects pressure by measuring the resistance change of a strain gauge. When pressure is applied to a strain gauge, its shape and size change, causing its resistance value to change.
  • Capacitive Pressure Sensor: In a capacitive sensor, the pressure changes the distance between two conductive plates or the dielectric constant of the medium, thereby changing the capacitance value.
  • Piezoelectric pressure sensors: When certain materials, such as quartz, are subjected to pressure, they generate an electrical charge. Piezoelectric sensors take advantage of this property to measure pressure.
