Product Description

Cheap Air Compressor Pressure Transducer for R410a,R22,R134a,R404a APT210/Oil Pressure Sensor

Product Description

APT210 pressure transmitter use the Germany Ceramic sensors or diffuse silicon oil-filled sensors body as the sensitive element, built-in processing circuit to change sensors millivolt signal to standard output voltage or current signals, can be directly with the computer, control instrument and display instrument, etc. Select the high stability, high reliability of piezoresistive pressure sensor and high-performance dedicated circuit in the transmitter, the overall performance is stable and reliable, long distance signal transmission can be performed. Adopts the integration of the full stainless steel structure, after lots of stainless steel welding to reach the solid-state design, easy installation, with the characteristics of high vibration resistance and impact resistance, can be use in the bad environment for a long time.

Our Services & Strength


1.The measuring medium must be compatible with 304 stainless steel and nitrile rubber.

2.If possible, the electrical connection of the pressure transmitter should be as vertical as possible. Measurement of dry gas pressure except indoors and in dry conditions;

3.When the pressure vessel being measured has a water or Air Hammer, a buffer valve must be installed at the front of the pressure transmitter interface.

4.When used to measure the pressure of the outlet of a pressure pump, a buffer valve or a buffer bend must be added at the front end of the pressure transmitter.

5.When a pressure transmitter is installed in the pipeline, the first step is to clean up the liquid at the threaded port and install the pressure transmitter. The second step is to slowly open the valve after installation to prevent pressure impact.

6.When a pressure transmitter is mounted on a turn pipe, it should be at least 9 times the diameter of the pipe at the turn and preferably downstream of the turn flow.

7.When a motor is present in the measuring system, ensure that the motor housing and the housing of the power supply for the pressure transmitter are at the same potential and that the resistance between the housing and the Earth does not exceed 9;

8.When there is a transducer in the measuring system, the shell of the motor controlled by the transducer should be connected to the ground wire of the power supply of the pressure transmitter.

9.When the pressure hole of the pressure transmitter is blocked, it is forbidden to use the sharp device to dredge the pressure hole. 10.The pressure transmitter should be dismounted and the part of the pressure hole should be immersed into the liquid that can dissolve the blocked material. If the user needs to calibrate zero or calibration full range should be under the guidance of our technical people, do not open the transmitter to adjust;

11.The pressure transmitter should be installed in a position that is not vulnerable to collision and trampling;

12.Transmission Cables for pressure transmitters shall not be placed in the same threading tube or in the same wiring groove as other high-voltage or high-voltage cables;

13.When installing pressure transmitters in the Dorey area, be sure to install lightning protection devices and ensure that the pressure transmitters and power supply are reliably connected to the ear;
