Overview
Health flat membrane type pressure transmitter
Product Details
Description:

ZW316W seriesHealth flat membrane type pressure transmitterIs specially designed for medicine such as medicine, food, beer, milk storehouse design in the field of special products, the design fully comply with pharmaceutical grade sanitary standard of food industry.Flush with large corrugated make measuring dielectric isolation combined with pressure sensor, which pump health and special oil, can guarantee no temperature drift at medium temperature of 150 ℃ high temperature stable work.Customer service on the industrial field at present commonly used flush the diffusion silicon or ceramic capacitance transducer as sensor direct contact with the medium, thus under the condition of high temperature large temperature drift, resulting in poor, especially in particular sterilization environment section of the transmitter is extremely easy to damage the ills.

Second, the working principle:

ZW316W series health flat membrane type pressure transmitter using diffusion and ion implantation technology form resistance and connect ChengHui stone bridge, with micro mechanical processing technology in the electrical bridge formation pressure sensitive film.When the pressure on the diaphragm, resistance to change and produce a is proportional to the applied pressure of the linear output signal.We are on the wheatstone bridge with dc power supply, can produce a dc voltage signal output.After a second crossover, realizes the two wire system 4 ~ 20 ma output.

Applications:

ZW316W series health type flat diaphragm type pressure transducer for the integration of all stainless steel flat membrane structure, designed for food, medical, pharmaceutical and health industry.The sensor plane membrane structure to prevent scale formation, not health and viscous liquid blocking problem.Widely used in food, pharmaceutical, brewing, and other areas of the process control.Its industry applications such as the following:

1, food hygiene industry;

2, pulp and paper industry;

3, water level measurement;

4, cans level measurement;

5, pipeline level measurement;

6, pharmaceutical and biological products processing.

Four, the main features:

1. Fast loading clamp: the form of product to take medicine, food and other industries general form of "CARDS" connection, high universality and interchangeability.

2.Beer special: into beer industry design, add extension condensing unit, can effectively prevent condensation at low temperature.

3.Pressure rotary type: the nut inside screw press process of spiral type connection, easy disassembling and cleaning.

4.Screw-plug: the external thread screw-plug process connection.

5.Flange: adopt the flanged process connections.

6.Conform to the standard type: this product is for medical industry in the U.S. FDA drug standard specialized design and manufacture of a new generation of transmitter.Perfect for stainless steel material.Its take thread screw-plug installed at the bottom of the form, and equipped with special health level for the customer material installed base, can install closely flush with the bottom of the tank, realize the real health no dead Angle.

Five, the technical parameters:

1, clean the planar isolation diaphragm, in line with international health standard; 3 a

2, use ceramic capacitance pressure sensor or diffusion silicon pressure sensor;

3, range: 0-4 kpa ~ 35 mpa;

4, power supply: 15-36 VDC;

5, temperature drift: 0.02% FS / ° C;

6, accuracy: 0.25%;

7, shell protection: IP65;

8, electrical connections, cable waterproof box type 2088 haltzman joint shell optional;

9, temperature: electronic circuit board work in - 40 ~ 85 ℃;Sensitive components work in - 40 ~ 104 ℃;Storage temperature - 40 ~ 85 ℃;With digital display - 25 ~ 65 ℃ (normal operation);- 40 ~ 85 ℃ (no damage);

10, relative humidity: 0 ~ 95%;

11, stability, zui range in a wide range of plus or minus 0.25% / 6 months.

12, vibration impact: in any axis upwards, frequency is 200 hz, error in a wide range of zui range of plus or minus 0.05% / g;

13, load effect: as long as the input voltage is higher than 12 v in the transmitter, the load work area without load;

14, installation location: zui can produce no greater than 0.25 kPa zero error, this error can be eliminated by correction, the range have no effect;Measure the ontology flange rotation relative to no effect.

Six, structure features:

1, the shell material: SUS304.

2, the diaphragm material: SUS316L, ceramic;

3, interface: 1?"Inch thread, DN articulated and flange connection;

4, lead way: aviation plugs, Hirschmann joint;

5, protection grade: IP65.

Seven, matters needing attention when using:

1 when the winter freezing, sanitary type pressure transmitter, anti-freezing measures according to the required in outdoor transmitter, without pressure, fluid due to the icing volume expansion in the mouth, lead to the damage of sensors.

2, connection, cable through the waterproof connector (attachment) or round tube and screw down the sealing nut, such as in case of rain through the cable leakage into the transmitter inside the shell.

3, when measuring the pressure of the gas, apply pressure to open at the top of the process piping, and health type transducer is installed in the upper part of the process pipe so that the deposition of liquid pipelines of rapid injection to the process.

4, sanitary type pressure transmitter measuring steam or other high temperature medium, the need to connect with the buffer tube (coil) such as condenser, should not make the transmitter operating temperature more than limit.

5, pay attention to the guide sensor pressure tube to install where small temperature fluctuations.

6, when measuring the liquid pressure, health type pressure transmitter installation location should avoid the impact of the fluid (water hammer), in order to avoid the sensor damage of overpressure.

7, when measuring the liquid pressure, pressure pipe side should be open in the process, in order to avoid precipitation product residue.

Eight, to prevent the health type pressure transmitter with corrosive or overheating of media contact, prevent the dross in intraductal deposition.
