DPD1T-./DPD2T-. is a Barksdale 24 series of mechanical 1 or 2 way differential pressure switches with a maximum working pressure of 28 bar and can be recalibrated. It is mainly used in machinery and tool manufacturing, pharmaceutical, pump control, refrigerant monitoring and other industries.
The DPD1T and DPD2T are metal‑membrane differential pressure switches designed for machine and tool building, autoclaves, pump control, cold‑media monitoring and shipbuilding applications. They feature adjustable set points during operation and are suitable for intrinsically safe installations.
Key specifications include a differential pressure range of 0.02‑10.2 bar, operating temperature from –40 °C to +75 °C, IP65 protection, and a maximum switching frequency of 20 switches per minute. The housing is anodised aluminium, the process connection is 1/8" NPT, and the electrical connection uses an internal terminal strip rated up to 28 V and 50 mA. This manual is written in German.
