TSSF212Y100 is a compact external mount device combining liquid level sensing with temperature measurement via a high-specification thermistor and 1/2"NPT thread connection. The device features stainless steel construction (SS 316 float and SS 304 stem) with a 25VA switching capacity, maximum switching voltage of 240V AC or 120V DC, and a maximum switching current of 0.6A. It operates over a temperature range of -20°C to +120°C with temperature sensing accuracy of ±0.2°C (0°C to +70°C), a thermistor nominal resistance of 10kO at 25°C, and a response time of less than 1 second. The device is designed for external mounting without requiring tank access, making it ideal for pharmaceutical, food and beverage, dairy, and biofuel industries where both level and temperature monitoring are critical.
