 PAD / PAS – Pressure Transmitter

Known for their reliability and high accuracy, the pressure transmitters of the PAD and PAS series for absolute, gauge and differential pressure are now approved for hazardous areas with both explosion protection Ex db, Ex tb and intrinsically safe Ex ia according to ATEX directives . This makes our PAD and PAS pressure transmitters suitable for even the most difficult applications for pressure, level and flow measurements.

PAD – Difference under control
✔ Measuring ranges: from 0.75….15 mbar up to 4.137….413.7 bar
✔ Process temperature: Max. 120 °C
✔ Materials: stainless steel, Hastelloy-C®, Monel, Tantalum
✔ Options: frequency output for totalisation

PAS – Where there is pressure
✔ Measuring ranges: from -1…1.5 bar to 0…600 bar
✔ Process temperature: Max. 120 °C
✔ Materials: stainless steel, Hastelloy-C®, Tantalum

KDF / KDG – Variable Area Flow Meter

The proven KDF and KDG flowmeters now offer also the option of a shortened installation length of 90 mm, to monitor the flow reliably and economically.

Features:
These simple and inexpensive measuring systems for liquids and air work according to the float principle: the installation position is vertical and the flow direction is from bottom to top. The float is a sphere, so the indication point is the upper edge of the sphere. A needle valve is fitted as standard.

Technical data:
✔ Measuring ranges:
Water 0.02 … 100 l/h
Air 2 … 3000 Nl/h
✔ Process temperature max. 100°C
✔ Process pressure max. 16 bars
✔ Wheelbase: 90mm

DUK – Ultrasonic Flow Meter

Ultrasonic waves provide precise volume flow measurements using the transit time difference. The instruments are bidirectional and can be installed in any position. The wide ratio between start and full scale of 1:250 is guaranteed by the new C3T0 electronics, which supplies the temperature measurement, also using it to compensate the flow measurement of viscous and non-viscous fluids.

General Features:
✔ Measuring ranges from 0.08…20 l/min up to 2.5 … 630 l/min
✔ Maximum fluid temperature: 90°C
✔ Maximum fluid pressure: 16 bar
✔ Installation in any position

C3T0 Electronics Features:
✔ IO-Link
✔ Flow and temperature measurement
✔ Instant measurement, totalization and dosing functions
✔ Dosing function with external control command
✔ TFT multi-parameter display, electronically rotatable in 90° steps
✔ Bi-directional measurement
✔ Intuitive setting menu via 4 optical keys, with quick access keys
✔ 2 individually configurable outputs (pulse/frequency/alarm and analog output)
✔ Partial and total totaliser
✔ Wide choice of fluids present in the database with the possibility of importing new ones according to customer specifications
