    Tips: Working Principle of the Tuning Fork Level Switch.

    The working principle of the tuning fork level switch is to make the tuning fork vibrate at a certain resonance frequency through a pair of piezoelectric crystals installed on the tuning fork base. When the tuning fork of the tuning fork level switch is in contact with the measured medium, the frequency and amplitude of the tuning fork will change. These changes of the tuning fork level switch are measured, processed and converted into a switch signal by the intelligent circuit.

    High Temperature Pressure Sensor for Steam/Fuel Oil

    This series of high temperature pressure sensors use a high-performance silicon piezoresistive pressure core as core element. The internal ASICs convert the mV signal into a standard current signal (4-20mA/0-20mA), voltage signal (0-5V/1-5V/0-10V) or RS485. Pressure sensor with stainless steel sealing structure has cooling fins, high anti-vibration and anti-shock performance, measuring range -0.1~100MPa/ -1~1000bar/ -14~14503psi, medium temperature -40~+300℃ (-40~+572℉), for steam/fuel oil/high-temperature liquid pressure measurement.
