| Options | Sensor remote with 3 m/9 ft cable Gas-tight feed through | |
| Application limits | High process temperatures (> 150 °C/302 °F) can favor diffusion of the process medium into the probe coating which may lead to a limited lifetime. FMP54 Interface measurement: Use coax system in favor (coax probe, bypass, stilling well) Interface with emulsion: FMP55 | |
