| The pressure within the Cryostat is monitored with a **Single Gauge TPG361** from **Pfeiffer Vaccum**, which uses a PKR 251 FPM-sealed, DN 25 ISO-KF gauge sensor. The maximum pressure applies to inert gases and temperatures below 55 °C and is corrosion resistant. The TPG361 is designed for installation to a 19“ rack chassis adapter according to DIN 41494 and provides serial communication via R485 (24V, 5-pin circular), USB and Ethernet interfaces.It is used to measure the pressure inside the chamber. | The pressure within the Cryostat is monitored with a **Single Gauge TPG361** from **Pfeiffer Vaccum**, which uses a PKR 251 FPM-sealed, DN 25 ISO-KF gauge sensor.
