UDE-508 Intelligent RF Capacitance Level Switch

Specifications

UDE-508 RF capacitance switch is intelligent level switch. It utilizes RF capacitance measuring technology and digital calibration technology and overcomes the two difficulties of great temperature drifts and hard calibration. “Digital calibration technology” is especially designed for this product and brings great convenience to end-users. It will further promote the capacitance level switch to be used in much wider in various industries.

This product is easy to operation with the setting press key to set the lower and upper limit. Flexible controlling method, normally close/open contacts can be chosen freely. It has overcome the shortcomings of probe rod attachments or material splashing which may affect measurement. Under these rug service conditions, UDE-508 capacitance switch can work normally. No moving elements in the checking parts, anti-shocking, insulted PTFE applied in probe rod; high temperature and high pressure resistance, anti-corrosion, not-easy being attached.
