Product details
Brief introduction:
HQ1151/3351/1151/3851DP double flange differential pressure transmitter is used to prevent the medium in the pipeline from directly entering the transmitter. The pressure sensing diaphragm is connected to the transmitter by a capillary tube filled with fluid. It is used to measure the liquid level, flow rate, and pressure of liquids, gases, or vapors, and then convert them into 4-20mA DC signal output.
HQ-3051DP/GP type differential pressure/pressure transmitter with remote transmission device
After the HQ-3051DP/GP transmitter is equipped with a remote transmission sealing device, it becomes the HQ-3051DP/GP remote transmission differential pressure/pressure transmitter.
HQ-3051DP/GP remote differential pressure/pressure transmitter is a reliable measurement method that avoids direct contact between the measured medium and the isolation diaphragm of the transmitter. It is suitable for the following situations:
When the tested medium has a corrosive effect on the transmitter connector and sensitive components;
When it is necessary to isolate the high-temperature measured medium from the transmitter;
When there are solid suspended solids or high viscosity in the measured medium that can easily block the transmitter connector and pressure chamber;
4. When the tested medium is easily solidified or crystallized when led out with a pressure tube;
5. When replacing the tested medium, it is necessary to rinse and not mix it together;
6. Hygiene conditions must be maintained to prevent contamination.
The HQ-3051DP/GP type remote differential pressure/pressure transmitter with remote sealing device still has various characteristics of the HQ-3051DP/GP type differential pressure/pressure transmitter.
Provide a variety of structural materials and welding structures for remote transmission device components, with strong reliability. The low volume design of the charging cavity reduces the impact of temperature changes. According to user requirements, the DC200 series silicone oil is filled with a temperature range of -40~+149C, and high-temperature silicone oil is filled with a temperature range of -20~+315C.
The upper limit of the working pressure of the remote transmission device is the rated value selected by the user, and the working pressure is not less than 3.5KPa (excellent pressure). The selection of isolation membrane materials for corrosive media can be found in the appendix, which is only for reference by users when selecting.
