FAQ – Presense ASL-7810 Float Switch

Q1: What is the operating principle of the Presense ASL-7810 Float Switch?
The ASL-7810 operates using a reed switch mechanism that is triggered by a magnetic float. As the liquid level rises or falls, the float moves accordingly, opening or closing the reed switch to signal level changes.

Q2: What materials are available for the ASL-7810 Float Switch?
It is available in SUS304 and SUS316 stainless steel versions. SUS316 is recommended for corrosive or chemical environments due to its higher resistance to oxidation and chemical attack.

Q3: Can the ASL-7810 be used in both conductive and non-conductive liquids?
Yes. The switch is suitable for use with both conductive and non-conductive liquids, including water, oil, fuel, and various industrial solutions.

Q4: What is the maximum temperature and pressure the switch can handle?
The ASL-7810 can operate between -20°C and +80°C and withstand a maximum pressure of 0.2 MPa, making it suitable for a wide range of industrial and environmental conditions.

Q5: How should the ASL-7810 be installed?
It should be installed horizontally on the tank side wall. Proper orientation and secure threading (M20, G1/2, or NPT 1/2) are essential for accurate level detection. Avoid excessive mechanical stress during installation.

Q6: What are the electrical characteristics of this float switch?
It features a Normally Open (A-type) contact, rated at 10 W, with a maximum switching voltage of 100 V (AC/DC) and a maximum switching current of 0.5 A.

Q7: Is the ASL-7810 suitable for outdoor or humid environments?
