Liquid flow switch 'LG01-2000A005'

Liquid flow switch 'LG01-2000A005'

Liquid flow and bubble detection, switching point at 0.25 ml/min! Improving system reliability.

The "LG01-2000A005" is a liquid flow switch that detects bubbles in micro-flow or fluid systems, enhancing the reliability of the system. The sensor's output signal indicates whether the measured flow rate is above or below a specified flow detection level with 0V or 5V output. In flow ranges exceeding the set value, bubbles can be detected by generating a low (0V) output. The product's measurement principle detects the current state of the fluid passing through the internal glass capillary. 【Features】 ■ Detects low flow rates at ml/min levels ■ Measurement is completely non-contact ■ Ultra-fast response: 100ms (response time) *For more details, please download the PDF or feel free to contact us.

Particle Flow Switch "KDS-1"

Particle Flow Switch "KDS-1"

A dust flow switch that captures the electrical properties of the measured object and outputs contact signals.

Unlike the Doppler method, it detects only the area around the electrodes, allowing for pinpoint detection without being affected by nearby rotating bodies or similar influences. It can be used for contamination prevention and quality control of mixed products through leak detection from bag filters and cyclones, clog detection, and flow/no-flow detection in air transport routes. Main features of the KDS-1 model: - As it is a contact type, it can measure low concentrations without being affected by changes in flow rate! - It has no moving parts, maintaining high functionality with minimal maintenance! - Alarm delay time can be set to prevent malfunctions! - Compact integrated design makes handling and adjustments easy! * The KDS-1 model is a contact type flow sensor, but there is also the KFD-1 model that detects flow non-contact.
