Description
Precise
The model P-30 and P-31 pressure transmitters have been developed for precision measurements. Through the use of a special WIKA pressure sensor, precision measurements with a maximum measuring deviation of as low as 0.05 % of span are guaranteed. Due to their active temperature compensa­tion these pressure transmitters have no additional tempera­ture error in the range of 50 ... 140 °F (10 ... 60 ° C).
Fast
The high measuring and output rates of up to 1 kHz make the measured value available as quickly as possible.
Compact
The compact design makes the pressure transmitter ideal for mounting into test benches, such as 19" racks.

Versatile
The models P-30 and P-31 oer a wide selection of electrical
connections, process connections, and measuring ranges, and output signals. In addition to the standard analog signals, USB and CANopen
Via a USB service interface and the WIKA conguration
software "EasyCom", the models P-30 and P-31 can quickly and easily be adjusted on site.
Thanks to the simple-to-use software "Wika data logger“, the USB version can also be used to save measured values and create customised reports.
versions are also available.
