Temperature Indicators

Capacitance level indicator Utilizes the capacitance formed between the sensing probe and the metallic vessel wall. A high frequency sine-wave is applied between the probe and the vessel wall. A change of the medium level will induce a change in the current of the applied sine-wave. From Z.Y..fact, when the capacitance in the vessel increase, impedance will decrease and anent will increase. Vice-versa, when the capacitance in the vessel is small, the impedance will increase and current will decrease accordingly.

Features :

• Suitable for high temperature, high pressure and comssive environment
• Not affected by noisy, dusty, misty and changes in the temperature.
• No blind distance, ideal fordifferenttanks
• Economical for large tanks
• 4-20mAoutput compatible for mostcontrol systems and meters.
