This manual details the purpose, features, operation principle, specifications, dimensions, wiring and ordering information for the ZXK series rotary vane…
The ZXK series rotary vane level controllers are designed for monitoring or controlling the level of powder and granular materials in open‑top containers. They feature stainless‑steel and aluminum alloy construction, mechanical overload protection, selectable blade shapes, five‑stage sensitivity adjustment, and a heat‑dissipation design for high‑temperature use.
The manual provides the working principle (micro‑motor driven blade with micro‑switches), technical specifications such as blade speed, supply voltage, contact capacity, power consumption, temperature range, and weight, as well as installation guidance, wiring terminal diagrams, and ordering notes for different models and mounting options. This manual is written in Chinese.
| Blade speed | 5–6 rpm (standard) or 1 rpm (import motor) |
|---|---|
| Supply voltage | 24VAC, 36VAC, 110VAC, 220VAC, 50Hz, 24VDC |
| Contact capacity | 220V/3A (AC) / 250V 2A |
| Power consumption | < 3 W |
| Operating temperature range | -30 °C to +80 °C (up to 300 °C for R model) |
| Weight (ZXK‑1 model) | 2.0 kg |
| Sensitivity adjustment | Five stages (mechanism) |
| High‑temperature capability | Up to ≤300 °C for R‑type models |
When the material level rises and blocks the rotating detection blade, a micro‑switch triggers a signal and stops the motor; when the level drops, a spring returns the mechanism and the motor restarts.
The ZXK‑*R type model includes a heat‑dissipation device and can operate in temperatures up to ≤300 °C.
The controller provides five adjustable sensitivity levels (three levels for some models).
