The Low-Temperature Rigid Rod Magnetic-Inductive Level Gauges are innovative products with high precision and reliability, effectively addressing the challenges of liquid level and interface measurement under extreme working conditions. Utilizing magnetic-inductive technology ensures that the measurement process is unaffected by temperature, pressure, dielectric constant, and other factors. With its high precision, stability, and maintenance-free features, it effectively avoids the shortcomings of traditional electric float switches, differential pressure transmitters, and radar-based level products in field applications, making it widely used for high-precision level and interface measurements.

Product Structure:
The magnetic伸缩level gauge features a modular design, with a simple structure consisting of three parts:
Electronic Meters: Housing, Circuit Board, Electronic Module
Probe Rod Components: Probe, Sensor, Magnetostrictive Wire, Float
Accessory Components: Buoyancy Tanks and Top Flanges, etc.
Installation:
Avoid bending or damaging the liquid level probe rod during installation. If the probe rod bends, it will hinder the float's free movement along the rod, thereby affecting the measurement results. The installation steps are as follows:
1. Ensure the appropriate float size can smoothly fit into the buoy or mounting hole, as well as verify the suitability of related accessories.
2. The float is directly mounted to the probe rod of the level gauge and can move freely on the rod. When installing the float, ensure that the direction marked with "UP↑" aligns with the measuring direction.
3. Clean the probe rod and float of the level gauge, removing any attachments or stains.
4. Ensure alignment at the "0" point during installation. If the ordered product requires a fixed flange, install it directly on-site; if not, align the "0" point during on-site installation. When the level gauge shows 0mm, secure the level gauge to the installation flange.
5. When the process temperature exceeds 150°C, the probe rod at the top of the flange needs to be extended with a high-temperature bracket for better heat dissipation and reinforcement of the gauge.
6. Clean off any deposits or stains from the surface during the installation of the level gauge.
