This robust pressure sensor was specifically developed for applications where minimal dead volume and maximum media resistance are critical. The coated, flush-mount diaphragm effectively prevents buildup and carry-over, making it ideal for precise measurements in microreaction technology and laboratory environments.
Thanks to the PFA-coated contact surfaces and the optimized design, this sensor is the ideal choice for demanding chemical reactions where metal ions could interfere with the process or aggressive acids would corrode conventional sensors.
The low-dead-volume pressure sensor consists of a pressure transmitter with a flush-mount diaphragm for various measuring ranges and a pressure cell made of PEEK or ECTFE.
