Explosion proof intelligent pressure transmitter

1Explosion proof intelligent pressure transmitterThe working principle is to detect the weak non electric voltage sensed by the sensor—The pressure variable is converted into a standardized signal output that can be transmitted and amplified to supply secondary instruments such as indicator alarms, recorders, and regulators for measurement, indication, and process regulation. The converted electrical signal has a certain continuous functional relationship with the pressure variable (usually a linear function). The pressure transmitter mainly consists of three parts: sensitive components, sensing elements, and measurement conversion circuits.

IIIHANYOC-HYKDBPHAG1ZGMain advantages of pressure transmitters:

1, DedicatedV/IIntegrated circuits have fewer peripheral components, high reliability, simple and easy maintenance, small size, light weight, and extremely convenient installation and debugging;

2Aluminum alloy die-casting shell, three end isolation, electrostatic spray protection layer, sturdy and durable;

3The4-20mA DCTwo line signal transmission, strong anti-interference ability, and long transmission distance;

4TheLEDThe indicator head is very convenient for on-site reading. Can be used to measure viscous, crystalline, and corrosive media;

5High accuracy and stability. In addition to the imported original sensors that have been laser corrected, fine compensation is provided for the comprehensive temperature drift and nonlinearity of the entire machine within the operating temperature range.

IIIExplosion proof intelligent pressure transmitterDuring use, the following situations should be considered:

1When measuring liquid pressure, the pressure tap should be opened on the side of the process pipeline to avoid sedimentation and slag accumulation;

2When measuring gas pressure, the pressure tap should be opened at the top of the process pipeline, and the transmitter should also be installed at the top of the process pipeline to facilitate the injection of accumulated liquid into the process pipeline;

3The pressure conduit should be installed in a location with minimal temperature fluctuations;

4When measuring steam or other high-temperature media, it is necessary to connect a buffer tube (coil) or other condenser, and the working temperature of the transmitter should not exceed the limit;

5When wiring, thread the cable through the waterproof joint (accessory) or flexible tube and tighten the sealing nut to prevent rainwater and other substances from leaking into the transmitter housing through the cable.

Applicable occasions of diaphragm pressure transmitter:

1Viscous media at high temperatures;

2Medium that is prone to crystallization;

3Sedimentation media containing solid particles or suspended solids;

4Strong corrosive or toxic media;

5Can eliminate the occurrence of pressure pipe leakage and pollution of the surrounding environment; It can avoid the tedious work of frequently replenishing isolation fluid due to the instability of measurement signals when using isolation fluid;

6Continuous and precise measurement of interface and density;

7The remote transmission device can avoid the mixing of different instantaneous media, thus enabling the measurement results to truly reflect the actual situation of process changes;

8Places with high hygiene and cleanliness requirements;

9In the production of food, beverage, and pharmaceutical industries, not only is it required that the contact area of the transmitter with the medium meet hygiene standards, but it should also be easy to rinse to prevent cross contamination of different batches of media.
