Differential pressure transmitter TST-DD 40

TST-DD 40 differential pressure transmitters are designed to measure the differential pressure of many gases or liquids, such as water or oil. Despite the very high one-sided overload resistance and a maximum permissible static pressure of +40 bar, the smallest possible standard differential pressure measuring range starts already at 0 ... +50 mbar.
Areas of application for the TST-DD 40 are numerous industrial applications, for example in plant construction and automation technology, in hydraulics and pneumatics or in water technology. Due to the metallic measuring cell with 1.4404 stainless steel diaphragms, the TST-DD 40 can also be used in many chemical applications.

The precise measurement of the differential pressure is achieved by the use of an internal transmission medium. To avoid a position-dependent zero offset, the installation position of the TST-DD 40 (horizontal or vertical) must be specified when ordering. The standard differential pressure measuring ranges (ΔP) start at 0 ... +50 mbar and reach up to 0 ... +25 bar. The measured value is output as analog signal with 4 ... 20 mA, 2-wire. The permissible media temperature is in the range of -25 ... +120 °C, the total measurement error at room temperature is ≤ 0.2 % FS.

There are two types of process connection available. A G 1/2 "male thread made of 1.4404 stainless steel (316L) or a G 1/4" female thread made of the same material is available as a process connection for both pressure sides. The electrical connection can be selected from a variety of common connector variants, such as M12x1 or MVS/A.
