purpose

ZY3051LPDouble flange liquid level transmitterIt is a method of sensing the measured pressure through a remote transmission device installed on a pipeline or container. The pressure is transmitted to the transmitter body through a capillary filled with silicone oil (or other liquid), and then converted to 4-20mA by the delta chamber and amplification circuit board inside the transmitter body DC signal output (see schematic diagram).
ZY3051LPdifferential pressure transmitterCombined with an intelligent amplification board, it can form an intelligent remote transmission pressure and differential pressure transmitter. When paired with a handheld device that complies with the HART protocol, it can communicate with each other for setting and monitoring.
In order to meet different installation requirements, this series of transmitters has multiple forms of remote transmission devices for users to choose from, and the main structure of the transmitter is the same as the differential pressure.

Remote transmissionTransmitterMainly used for measurement in the following situations

Viscous medium at high temperature
Easily crystallizable medium
Settling media with solid particles or suspended solids
Strong corrosive or highly toxic media
Can 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.
Continuous and precise measurement of interface and density
The 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.
Places with high hygiene and cleanliness requirements
In 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.

Product Features

Simulate "online operation" assessment for each transmitter to ensure stable and reliable operation under extreme environmental temperature, medium temperature, and working pressure (including positive pressure or vacuum).
Adopting a "dynamic profile" remote transmission membrane structure, the membrane will not be damaged after overload; The accuracy will not change after long-term work.
The use of a full fusion welding and rigid sealing structure filling system has eliminated the occurrence of oil leakage.
A novel capillary coupling component is designed to provide reliable protection for the capillary, making it less prone to breakage during on-site use.
A variety of remote transmission devices in terms of variety, form, and size, as well as a rich variety of filling fluids, can meet the measurement needs of various occasions.
We can provide various special needs products, including high temperature, high vacuum, fast response, and unequal long capillary (difference ≤ 4.5 meters) remote differential pressure transmitters.

Indicator (%): LCD digital display accuracy ± 0.2% Vibration effect: ± 0.05%/g when vibrating at 200Hz in any direction. Installation position: The diaphragm is not installed vertically, which may result in a zero point error of less than 0.24KPa, but it can be corrected by adjusting the zero point. Weight: 3.9Kg (excluding accessories) Note: The static pressure of the remote differential pressure transmitter also depends on the specifications of the selected flange. ② The working temperature of the remote transmission device is determined by the type of filling fluid selected. ③ The influence of medium temperature on remote differential pressure transmitters refers to the output changes caused by the same temperature acting on both sides of the remote transmission device starting from room temperature. ④ The effects of static pressure and temperature were measured at the maximum range. ⑤ The maximum length of the capillary tubes on both sides of the DP type remote differential pressure transmitter is 7.5 meters, with a length difference of 4.5 meters between the two sides.

Remote differential pressure transmittermodel selection

Remote transmission transmitter is a variant product that adds a remote transmission device to the transmitter body, so its selection work can be carried out in two steps: first, determine the type (DP), measurement range, and structural materials of the transmitter body, and then determine the type and size of the remote transmission device according to the installation requirements on site. Due to the close relationship between the various parameters that make up the filling system (such as the working temperature, viscosity, and capillary length of the filling fluid) and the performance indicators of the transmitter, they are included in the selection category of the transmitter body and are not separately listed for selection.
