The ifm efector LT Series Electronic Level and Temperature Sensor features capacitive measuring technology housed in a stainless steel probe with a 16mm diameter, equipped with a 4-digit alphanumeric display and programmable buttons for on-site configuration. These sensors are suitable for monitoring hydrous coolants, oils, oil-based media, water, and similar fluids with a dielectric constant greater than 2, operating within a voltage range of 18 to 30 VDC with current consumption below 50 mA and reverse polarity protection. They also feature thermal and pulsed short-circuit protection with a power-on delay time of less than 3 seconds.
