IMRET series analog temperature sensor

The IMRET series is a liquid level sensor that also continuously monitors temperature. These sensors provide two separate analog signals (4–20 mA): one for liquid level and one for temperature. This makes them ideal for installations where dual monitoring is necessary, such as fuel tanks, generators, hydraulic reservoirs, and industrial storage tanks.

The housing is made of anodized aluminum, with a stainless steel AISI 304 variant available on request. The internal rod is made of steel and the float is made of NBR, making the sensor suitable for use in water, mineral oils, diesel, and gasoline. Thanks to its high degree of protection (IP65) and an operating temperature range of -20 °C to +80 °C, the IMRET can function reliably in demanding conditions.

In addition, various electrical connections are available, including aluminum junction boxes and an optional M12 connector.
