Pressure sensors can be classified from different perspectives: their conversion principles (basic physical or chemical effects of pressure sensor work); their purpose; their output signal types and t...

The temperature measurement range of Capillary Thermometer is 200~650℃ (also clearly recorded in the encyclopedia), and the allowable error is about 1% of the scale range.

The refrigerant pressure gauge must be vertical: during the installation process, use a wrench to tighten, and the shell must not be twisted; avoid collision during transportation.

The temperature range of the outdoor metal thermometer is 200~650℃, and the allowable error is about 1% of the scale range.

Diaphragm pressure gauge is suitable for measuring the pressure of the medium with strong corrosion, high temperature, high viscosity, easy to crystallize, easy to solidify, and solid floating matter.

The working principle of the reflex type level gauge is based on the different reflectivities of steam and liquid.

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...
