Differential Pressure Transmitter DPS 300

The DMD 341 is a differential pressure transmitter for non-aggressive gases and compressed air. Because of its compact and robust aluminium housing it is suited for machine and plant engineering. Basic element is a piezoresistive stainless steel silicon sensor, which features high accuracy and excellent long term stability. In combination with our display and switching unit ASM 430 the user has a 4-digit LED-display for representing the differential pressure as well as up to 2 freely configurable contacts. Features: — differential pressure 0 ... 6 mbar up to 0 ... 1000 mbar — accuracy: 0.35% / 1% / 2% FSO — piezoresistive silicon sensor — compact and robust aluminium housing — suited for non-aggressive gases and compressed air — current and voltage output signals in 2- and 3-wire systems Optional Features: — display and switching module with up to 2 contacts — customer specific versions

Features: — differential pressure 0 ... 6 mbar up to 0 ... 1.000 mbar — accuracy: 1 % FSO — piezoresistive pressure sensor

The differential pressure transmitter DPT 100 has been especially designed for fast test processes in leakage and flow measurement, where a fast response time and high sampling rate are necessary. The compact design of the DPT 100 facilitates the use in standardised applications, e. g., and the installation in 19“ Rack. The DPT 100 with optionally RS485 interface uses the communication protocol Modbus RTU which has found the way in industrial communication as an open protocol. The Modbus protocol is based on a master Slave architecture with which up to 247 Slaves can be questioned by a master – the data will transfer in binary form. Features: — differential pressure from 10 mbar up to 20 bar — static pressure max. 400 bar — accuracy: 0.1 % FSO — output signal 4 ... 20mA / 2-wire — aluminium housing, die casting Optional Features: — output signal RS485 with Modbus RTU protocol — several process connections

The differential pressure transmitter DPT 200 has been especially designed for the process industry and can be used for level measurement of closed, pressurized tanks, pump or filter controlling, etc. The possibility passes different pressure seals at the DPT 200 adding with different membrane materials to reach an optimal adaptation to the application. Features: — differential pressure von 1 mbar bis 20 bar — static pressure bis max. 400 bar — turn-down max. 100:1 — accuracy: 0.075 % FSO — HART®-communication — output signal: linear or square root extraction — aluminium housing Optional Features: — IS-version: Ex ia = intrinsically safe Version (group II) EX ia= intrinsically safe Version for firedamp mines (group I) Ex d = flameproof enclosure (group II) — LC-Display — stainless steeel housing
