4 20mA PNP NPN output flush membrane electronic pressure switch with LED light
Product Description
The new generation of PS858 transmitters was developed in close coordination with the users. Its modern and userfriendly design stands out. High overload protection and best accuracy.
PS858 is a pressure transmitter with a pressure switch to safely and absolutely measure and monitor gauge pressures. It is highly stable and has a function check and onsite information due to its OLED and digital display. It can be rotated up to 350° if placed on the upper part of the house, also the display contents can be rotated up and down.

Measuring range and limit |
Nominal value | Smallest calibratable span | Lower range limit (LRL) | Upper range limit (URL) | Overload limit |
40kPa | 10kPa | -40kPa | 40kPa | 1MPa |
250kPa | 25kPa | -100kPa | 250kPa | 4MPa |
1MPa | 100kPa | -100kPa | 1MPa | 6MPa |
3MPa | 300kPa | -100kPa | 3MPa | 15MPa |
Above measurement range can be replaced by kg/cm2, MPa and kPa units .Which can provide other measurement range according to the requirements. Adjust requirements: lower range value (LRV) and upper range value (URV) can be adjusted within the scope of the upper and lower range limit, smallest calibratable span≤|URV-LRV| ≤ upper range limit |
