Hygienic diaphragm pressure transmitter

I. Product Overview:

ZW3051TF series hygienic diaphragm pressure transmitter is specially designed for medicine, beer, milk barn and other medical and food fields. The series adopts E+H professional technology, and its design fully complies with the hygienic standards of the pharmaceutical and food industry. The pressure transducer interface is clamped, M27 * 2, and flange type is optional. The planar membrane structure of the sensor prevents scaling, unsanitary and viscous liquid clogging.

II. Working Principle:

The principle of ZW3051TF series hygienic diaphragm pressure transmitter is a capacitor consisting of measuring diaphragm and electrodes on both sides of insulating sheet. When the pressure on both sides is inconsistent, the displacement of the diaphragm is proportional to the pressure difference, so the capacitance on both sides is different. Through oscillation and demodulation, the diaphragm is converted into a signal proportional to the pressure, and then transformed into a standard electrical signal through temperature compensation and linear correction.

3. Application occasions:

ZW3051TF series hygienic diaphragm pressure transmitters meet the requirements of GMP and are suitable for hygienic level systems. In such systems, the medium can not be contacted with the instrument measurement system. The diaphragm seal will not produce dead angle or empty area. This kind of instrument has the advantages of quick disassembly, convenient assembly, non-pollution, easy cleaning, beautiful appearance, safe and reliable technical performance. It can be widely used in pharmaceutical, food, beverage, cheese making, water treatment and other industrial production. It is not only required that the contact medium parts of the transmitter meet the hygienic standards, but also should be easy to wash, so as to prevent different batches of media. Qualitative cross-contamination.

Fourth, main characteristics:

1. Fast-loading chuck type: This product adopts the general "fast-card" connection form of medicine and food industry, which has good versatility and strong interchangeability.

2. Beer-specific type: Converting to beer industry design, adding lengthening condensation device can effectively prevent low temperature condensation.

3. Spinning type: It is easy to disassemble, assemble and clean by using the spinning process of nut internal thread.

4. Spin-in type: The process connection of external thread spin-in type is adopted.

5. Flange type: Flat flange type process connection is adopted.

6. FDA Standard Formula: This product is a new generation transmitter specially designed and manufactured to meet the FDA pharmaceutical standards in the pharmaceutical industry of the United States. It is made of stainless steel. It adopts the screw-in type bottom installation form and equips customers with special hygienic grade material to install the base, which can be installed safely and tightly with the bottom of the tank, so as to realize the real sense of hygiene without dead angle.
