11.5 Process
11.5.1 Process temperature range
–20 to +85 °C (–4 to +185 °F)
The sensor can be exposed to process temperatures up to 130 °C (266 °F) without being
damaged. The monitoring system switches off automatically at T ≥ 85 °C (185 °F) and starts
again at T ≤ 85 °C (185 °F).
11.5.2 Process pressure range
Maximum permissible process pressure P
max
≤ 10 MPa = 100 bar (1 450 psi)
The maximum process pressure for the conical metal-metal process connection (MB
option) for the device is 1.6 MPa = 16 bar (232 psi).
