differential pressure transmitter

De-tails

PT717-BA differential pressure transmitter uses advanced micro-silicon solid-state composite sensor, adopts modular design, and consists of sensor module with integrated electronic adaptation unit and amplifier with button control unit.The sensor of PT717-BA differential pressure transmitter is a dual-cavity system with all welded sensor modules, which has an integrated overload diaphragm, an internal differential pressure sensing chip, an internal absolute pressure sensing chip and a temperature measuring element. The absolute pressure sensing chip only feels the pressure on the high pressure side as a reference value for static pressure compensation. The low-voltage side of that differential pressure sen chip is connected with the low-voltage side of the transmit through a capillary tube. The measured process differential pressure is transmitted through the isolation diaphragm and filling liquid.When the differential pressure sensor chip is supplied, the resistance of the micro-silicon solid-state differential pressure sensor chip changes slightly, which further leads to the change of the output voltage of the detection system. The output voltage is proportional to the process differential pressure and is converted into a standard output signal by the adaptation unit and amplifier.

Standard parabolic plug

For laminar or turbulent flow, the single-stage, dirt-resistant parabolic plug is the best choice. In the case of globe control valves without pressure balancing and up to nominal size DN 100 (4″), the plug and stem are one-piece; for higher sizes, the design is two-part. As standard, the characteristic curve of the parabolic plugs is adjustable; the standard characteristics curves are linear and equal percentage. The valve sealing is metallic type with Class IV leakage (Class V as an option). In order to counteract the cavitation-related erosion phenomena occurring under high pressure conditions, parabolic plugs (single or multi-stage) and clamping seat can also be made of highly wear-resistant ceramic materials. Noise emissions can be reduced with a low-noise perforated cage.
