The switch operates from a 24 V supply with a tolerance of ±10 %.
It can measure pressures from 0‑1 MPa in the low range and up to 0‑80 MPa in the high range.
For pressures below 10 MPa, two decimal places are allowed and the third digit can be 0 or 5; for pressures above 10 MPa, two decimal places can be set arbitrarily.
The device works from –20 °C to 85 °C.
