Differential Pressure Transmitter DPT 100

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 pressure transmitter DPS 300 was developed for the differential pressure measuring for dry, non aggressive gases and compressed air and can be used for several HVAC applications. The DPS 300 is a multi range transmitter with up to three adjustable ranges. The device is equipped with a two-line LC display optionally and can simply parameterised. Values, status of the contact and the unit are shown on the display. Features: — differential pressure 0 ... 1.6 mbar up to 0 ... 1.000 mbar — accuracy: 0.5 % FSO BFSL — current and voltage output signals in 2- and 3-wire systems — adjustable ranges — adjustable damping Optional Features: — LC-display, two-line — automatic zero adjustment — contacts (only in combination with display) — square root extraction (only in combination with display)

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
