Static pressure transducer, also called static pressure transmitter, is the pressure transducer with the current output pressure,
which can be the digital pressure trasmitter, or the piezoelectric pressure transmitter.
Static pressure transducer for pressure measurement, can be used for pipe, outdoor.
SI3051HP high static pressure transmitters, with working static pressure up to 25,32Mpa.
High Static Pressure sensors are for use with pressure gauges, switches, transmitters,
and other controllers，
to pick up or sense static pressure drop across air filters,
and cooling coils, blower input and discharge pressures, etc.
The high static pressure transmitter,
is used to measure the liquid level, flow, and pressure of the liquid,
gas or steam under high working pressure,
and then convert to 4~20mA DC signal output.
The high static pressure transmitter can measure differential pressure below 32MPa static pressure,
with 32MPa working pressure and overload protection,
ensuring reliable application of the transmitter in high static pressure systems.

What is a static pressure sensor?
The Static Pressure Sensor is a differential pressure sensor,
designed to monitor the difference in pressure,
between the inside and outside of a building.
In ventilation systems, static pressure is the pressure exerted by the air inside a building,
relative to the outside air pressure, when exhaust fans are turned on.
Measuring and maintaining proper negative pressure,
allows the ventilation system to mix outside air with inside air more efficiently and effectively.
High static pressure transmitter fault debugging steps:
1. Check if the power supply of the differential pressure transmitter is reversed,
and whether the positive,
and negative poles of the power supply are connected correctly.
2. Measure the power supply of the transmitter,
whether there is 24V DC voltage;
it must ensure that the power supply voltage to the transmitter is ≥12V
(that is, the voltage of the transmitter power input terminal is ≥12V).
If there is no power supply, check whether the circuit is disconnected,
whether the instrument is selected incorrectly
(input impedance should be ≤250Ω), and so on.
3. If the pressure transmitter is equipped with a meter head,
it is necessary to check whether the meter head is damaged
(you can short-circuit the two wires of the meter head first. If it is normal after a short circuit, it means the head is damaged).
If the meter head is damaged, Then you need to change the header.
4. If there is a problem with the differential pressure transmitter,
connect the ammeter to the 24V power supply circuit to check if the current is normal.
If it is normal, the transmitter is normal.
In this case, check if other instruments in the loop are normal.
5. Connect the power supply to the transmitter power input terminal,
and connect the power cable to the power supply wiring port.
