Differential pressure transmitter - Import export

The pressure transmitter DMK 456 has been developed for measuring the pressure in systems and the level in tanks and is as a consequence certificated for shipbuilding and offshore applications. Due robust stainless steel field housing and the possibility to use the device in intrinsic safe areas (temperature class T6) enable to measure the pressure of aggressive gases and fluids under extreme operating conditions. The basis for the DMK 456 is a capacitive ceramic sensor element designed by BD\SENSORS, which offers a high overload resistance and medium compatibility. Features: — nominal pressure: 0 ... 40 mbar up to 0...20 bar — accuracy: 0.25 % (opt. 0.1 %) FSO — shipping approvals: ABS, BV, CCS, DNV, GL, LR — IS-version (temperature class T6), Ex ia = intrinsically safe for gases — high overpressure capability — robust stainless steel field housing Optional Features: diaphragm AI2O3 99.9%

The DMD 331 is a differential pressure transmitter for industrial applications and is based on a piezoresistive stainless steel sensor, which can be pressurized on both sides with fluids or gases compatible with SST 1.4404 and 1.4435. The compact design allows an integration of the DMD 331 in machines and applications with limited space. The DMD 331 calculates the difference between the pressure on the positive and the negative side and converts it into a proportional electrical signal.

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

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
