Continuous measurement of liquid level in 5mm steps, with built-in temperature sensor for measuring liquid temperature. Five types of measurement lengths are available: 50, 150, 300, 600, and 900mm.
This is a continuous liquid level sensor with a built-in temperature sensor. By adopting a magnetoresistive element and using a ladder output method, we have achieved cost reduction. It is optimal for applications requiring liquid level control, detection of freezing, and temperature regulation of liquids. It supports longer measurement lengths than the HL-AP, with types available in 600 and 900 mm. By connecting to the dedicated display unit HL-AM of the HL-A/AP series, it is possible to display the liquid level position and liquid temperature. *For more details, please refer to the PDF materials or feel free to contact us. ▼ Contact Information TEL: Hamamatsu Office 053-420-1281 MAIL: info@watty.co.jp

Company information
Our company (formerly known as Keihin Sokkiki Co., Ltd.) was reborn as Watty, Inc. on January 1, 2007, marking our 40th anniversary. The company name combines "watt," a familiar unit of power associated with our main manufacturing division, the Thermal Systems Division (which develops, manufactures, and sells heater units used primarily in semiconductor and FPD manufacturing equipment and various precision instruments), and "water," representing the liquid typically sensed by our other main division, the Sensor Division (which focuses on the development, manufacturing, and sales of liquid level sensors). Thus, we chose the name Watty to reflect these two pillars.
