This document describes the D1T-./D2T-. model of metal membrane pressure switch. The product features a highly precise switching system, adjustable switching point, and is suitable for applications in machinery manufacturing, pump control, refrigerant monitoring, chemical industry, and more.
The Barksdale D1T-/D2T- series are metal‑membrane pressure switches designed for applications such as machine tool, autoclave, pump control and chemical industry. They feature a stainless‑steel (17‑7PH / SS304) membrane, IP65 protection and a temperature operating range from –40 °C to +75 °C.
Technical data include selectable pressure ranges from 0.005 bar up to 10.3 bar, electrical limits of 28 V max and 50 mA max, and a maximum switching frequency of 20 cycles per minute. The switches are available with 1/4" NPT or optional 1/2" NPT process connections and weigh approximately 1.0 kg (D1T) or 1.1 kg (D2T). This manual is written in German.
