The differential pressure transmitter is a device used to monitor the working status of filters. It determines whether the filter needs to be replaced or cleaned by detecting the pressure difference changes at the inlet and outlet of the filter. Filters are very important components in many industrial and commercial applications. Using a filter differential pressure transmitter can improve the efficiency and reliability of the system, while reducing maintenance costs.

There are many types of differential pressure transmitter used for hydraulic filter, such as CS-V pressure transmitter, Pressure switch ST307-350-B. As a professional supplier of the CS-V pressure transmitter, Yoyik has some useful knowledge about the pressure transmitters to share with you.

Operating principle of filter differential pressure transmitter

The working principle of the filter differential pressure transmitter is very simple, mainly including the following steps:

1. Detection of differential pressure: The filter differential pressure transmitter will install differential pressure sensors at both ends of the filter inlet and outlet, and determine whether the filter needs cleaning or replacement by detecting the differential pressure changes at the inlet and outlet.

2. Sending signal: When the pressure difference exceeds the preset value, the filter differential pressure transmitter will automatically send a signal to remind the user of the need for maintenance and repair.

3. Alarm prompt: The filter differential pressure transmitter is usually equipped with an alarm device, which can send an alarm through sound, light, and other means to remind the operator of corresponding processing.

Application of Differential Pressure Transmitter

Due to its convenient use, accurate alarm, and fast reading, differential pressure transmitters are widely used in various industrial and commercial applications, such as:

1. HVAC system: The transmitter can be used to monitor the status of filters in the air handling system to improve the efficiency and reliability of the system.

2. Vehicles and ships: Differential pressure transmitters can be used to monitor the oil, air, and water filters of the engine to ensure the normal operation of vehicles and ships.

3. Medical equipment: Filter differential pressure transmitter can be used to monitor filters in medical equipment to ensure the normal operation of the equipment and the safety of patients.

4. Industrial production: Differential pressure transmitters can be used to monitor filters during production to ensure product quality and production efficiency.

Application of Filter Differential Pressure Transmitter in Power Plants

In addition to the industries mentioned above, the differential pressure transmitter is also a necessary component in power plants to monitor the pressure and filter of the fire-resistant oil system. There are the following application channels in power plants:

1. Air filter: The filter differential pressure transmitter can monitor the differential pressure change of the air filter. Once the differential pressure exceeds the set value, an alarm signal will be sent to remind the operator to replace or clean the filter.

2. Circulating water filter: Circulating water filter is usually used to filter impurities and particles in water to protect the normal operation of equipment such as water pumps and heat exchangers. The filter differential pressure transmitter can monitor the differential pressure change of the circulating water filter and send an alarm signal when the differential pressure exceeds the set value to remind the operator to replace or clean the filter.

3. Steam filter: The filter differential pressure transmitter can monitor the differential pressure change of the steam filter and send an alarm signal when the differential pressure exceeds the set value to remind the operator to replace or clean the filter.
