1. How to connect a differential pressure transmitter to measure negative pressure? Differential pressure transmitters are usually used to measure pressure differences. To use a differential pressure transmitter for measuring negative pressure (i.e. vacuum degree), it is necessary to correctly connect its high pressure side (H) and low pressure side (L). The following is the connection method of differential pressure transmitter when measuring negative pressure: 1. Connect the high pressure side (H) of the differential pressure transmitter to the high pressure point in the measured system. 2. Connect the low pressure side (L) of the differential pressure transmitter to the low pressure point in the measured system. In this way, the output signal of the differential pressure transmitter will reflect the negative pressure value. To ensure accurate measurement, please follow the following precautions
1. Ensure that the pipeline between the high and low pressure points of the measurement system is well sealed to prevent leakage
2. Use appropriate pipelines and joints to ensure that the pressure of the measurement system does not cause damage to the differential pressure transmitter
3. When installing the differential pressure transmitter, ensure that it is installed vertically to avoid affecting the measurement accuracy
4. Provide a stable power supply for the differential pressure transmitter and ensure that it is well grounded to prevent interference.
. After completing the connection, you can use a display or data acquisition system to read the negative pressure value based on the range and output signal of the differential pressure transmitter (usually 4-20mA). During the operation, please

3.hi What do hi and lo mean respectively?
What do the Hi and LO ports mean on a differential pressure level transmitter? In a differential pressure level transmitter, the Hi and LO ports represent high and low pressure ports, respectively. The differential pressure level gauge determines the height of the liquid level by measuring the pressure difference between the upper and lower sides of the liquid level. Hi port receives high voltage signals, LO port receives low voltage signals. Usually, the high-pressure end of a liquid or gas is connected to the Hi port, and the low-pressure end is connected to the LO port. The working principle of a liquid level gauge is to measure the pressure difference on both sides and calculate the height of the liquid level. The connection method between the high and low pressure ends depends on the specific level gauge model and manufacturer. When installing and using a liquid level gauge, it is necessary to ensu
