Korea’s top class Flow and Level Instruments manufacturer with 45 years of history
Overview
HTM-30N Series is a Vibration Type Level Switch which is generally calling as Tuning Fork type consisting of a membrane and stainless steel tuning forks. It outs relay contact signal after detecting of liquid or solid level in the tank and can be especially applied for alarm and process control, etc..
Characteristics
- Digital operating system based on Microprocessor.
- Detecting of various kinds of liquid and solid level.
- Activation Point User Setting function.
- Applicable to Interface measurement.
- Applicable to Measurement Range Setting.
- Adjustment function with Delay and Return Time of Relay.
- Switching function between Relay Contact type. (NO, NC)
- Self-diagnosis function.(Diagnosis of state of sensor with current vibration frequency)
- Easy setting, stable operating and improved maintenance by dial adjustment.
- Easy operating check through LED indicator.
- Solid structure and applicable for small process connection due to Mini Tunning Fork.
- AC Free voltage or DC 24V is available.
- Monitoring function through laptop and/or mobile phone connecting using USB port.
Operation Principle and Composition
Tuning fork of the level switch is continuously vibrated by the oscillator or piezo sensor. When the tuning fork is contacted by the medium, the oscillator of piezo sensor is stopped by decreased vibration frequency. At this moment, level switch detects the changed frequency and produce a replay output signal.
