Applications of Electronic Pressure Switch:
Measurement and control of pressure/differential pressure of fluid
media in industries such as hydropower, metallurgy, and chemical
engineering, for automatic control applications.
1. When selecting the product, please ensure that the measured
medium is suitable for the contact part of the product.
2. When ordering, please indicate the power supply, precision
level, number of control points, whether with RS485 interface.
3. For users who choose differential pressure measurement,
attention should be paid to the relationship between the
differential pressure range and the allowed overpressure and
maximum pressure of the high and low pressure chamber, and ensure
that it meets the requirements of field applications. In order to
ensure the safe and reliable operation of the product, it is
recommended to install a three-valve manifold between the measuring
point and the transmitter.
4. In order to ensure the reliable operation of the product, it is
recommended to install the lightning protection device on the site
and ensure the reliable grounding of the product and the power
supply.In case of strong vibration, instantaneous impact force,
strong electromagnetic interference, radio frequency interference
and other special requirements, please inform us and indicate in
the order.
