### 🔧 Key Features
* *Three-Element “Coat Guard” Technology*: eliminates errors due to build-up on the probe by isolating sensing current solely through the true media
* *Configurable for High/Low Level Switching*: flexible in-field logic selection.
* *Robust Construction*: powder-coated aluminum sensor housing (IP65/IP66 equivalent), designed for harsh environments
* *Probe Options*: stainless steel rod, cable, flange mount; insulated with PTFE, PPS, with high-temp ceramic available; operates from –40 °C up to 200 °C (ceramic up to 800 °C)
* *Control Electronics*:
* AC or DC supply (90–265 VAC / 24 VDC).
* Two SPDT relay contacts, 5–10 A capacity.
* Adjustable delay (1–20 s).
* LED indicators: green for normal, red for alarm, yellow for power-on.
* *High Reliability*: immune to material bridging and build‑up shocks; fast installation and calibration with field-selectable logic
