Fire extinguisher is one of the common fire extinguishing equipment. Many people may know how to use a fire extinguisher but do not know how to read a fire extinguisher pressure gauge.

The basic principle of nautical quartz clocks is that the period of the pendulum remains unchanged. the pendulum moves one cycle, and the second hand moves once or twice.

The marine pressure gauge must be vertical: tighten with a wrench during installation, and do not twist the shell; avoid collision during transportation.

The high pressure gauge should be installed perpendicular to the horizontal plane to facilitate observation and maintenance; the installation height of the ordinary pressure gauge is flush with the li...

Oil filled pressure gauge is suitable for ships and other industrial equipment to measure the pressure of the medium with strong corrosion, high temperature.

As an online display instrument, the temperature range of a metal digital thermometer is usually (-50~1000)°C. It is equipped with platinum resistance or K-type thermocouple sensor as temperature meas...

Electric contact Bimetal thermometer is an on-site detection instrument suitable for measuring -80℃～+500℃, used to directly measure the temperature of gas, liquid, steam and other media and display it...

The 9" Industrial thermometer should be used in an environment where the ambient air temperature is -10oC- +55oC and the relative humidity is not more than 95%.

First check whether there is signal interference around the pressure transmitter. If there is, try to eliminate it, or connect the sensor shielding wire to the metal shell as much as possible to enhan...

The pressure gauge for oxygen cylinder cannot be adjusted. After the switch of the oxygen cylinder is turned on, the pressure gauge and the oxygen cylinder are connected.

The pt temperature sensor technology is very mature. The temperature sensor is often used in conjunction with some instruments, and there are often some minor faults in the supporting use process

Due to different structures, the capsule pressure sensor can be divided into measuring absolute pressure, relative pressure with respect to the atmosphere and pressure difference.
