DSU, DSI: Pressure transmitter

Product catalog summary

Overview: The document provides technical specifications and operational details for the DSU and DSI pressure transmitters, designed for measuring pressure in liquids, gases, and vapors. These devices convert pressure into a proportional standard signal, enhancing energy efficiency.

Features:

Measures pressure in various media with high precision.
Equipped with a sturdy ceramic diaphragm and stainless steel pressure sensor for corrosive environments.
Offers high positive pressure protection, vibration resistance, and low hysteresis.
Standard output signals of 2...10 V or 4...20 mA.
Complies with DIN EN 175301-803-A for plug connections.

Technical Data:

Power Supply: Two-wire (24 V=, 0.7 W) and three-wire (24 V=/~, 0.5 W).
Temperature Dependence: Zero point 0.07% FS/K, measuring range 0.05% FS/K.
Ambient Conditions: Temperature range 0...60 °C, medium temperature up to 85 °C, humidity 45...75% rh.
Construction: Chromium-nickel steel housing, IP65 protection, and CE conformity.

Standards and Directives: The device meets IP65 protection standards and conforms to CE directives, including EMC Directive 2004/108/EC.

Types and Specifications:

DSU models offer a measuring range from 0...2.5 bar to 0...25 bar with a 0...10 V output signal.
DSI models provide a similar range with a 4...20 mA output signal.

Operation: The pressure is applied to a ceramic diaphragm, causing deformation. This deformation alters the strain gauge output, which is converted into standard electrical signals by integrated electronics.

Intended Use: The product is intended for specific applications as described and should not be altered or converted.

Materials: Contact materials include stainless steel, ceramic, and fluoroelastomer seals.

Disposal: Disposal must comply with local laws, with further material information available in the product's environmental declaration.

Accessories: Includes capillary throttle and wall bracket options.

Product data sheet Measuring range (bar) Output signal Power supply Maximum pressure Accessories Description Capillary throttle, stainless steel, length 1 m, G½"-G½" Wall bracket for DSU/DSI Description of operation The pressure to be measured is exerted directly onto a ceramic diaphragm that deforms when pressure is applied. A strain gauge with a measuring bridge is fitted to the ceramic diaphragm. The deformation of the ceramic changes the output signal of the strain gauge. Electronics integrated into the device convert the bridge signals of the strain gauge into electric standard signals 4...20...
