Review LEEDS NORTHRUP And Temperature Potentiometer

The Leeds and Northrup 8694-2 Temperature Potentiometer is a high-precision, temperature-sensing device designed for laboratory and industrial applications. This potentiometer employs a bimetallic element to convert temperature changes into electrical resistance, which in turn produces a proportional voltage output.

The 8694-2 model features a temperature range of -65 C to 150 C (-85 F to 302 F), making it suitable for use in a wide variety of environments. The resistance range of this potentiometer is 25 ohms at 25 C (77 F), with a maximum power rating of 1 watt.

This temperature potentiometer boasts an outstanding level of accuracy and stability. The typical temperature coefficient is 0.02% per degree Celsius, ensuring precise temperature readings. Additionally, the potentiometer has a low hysteresis, which minimizes the effects of temperature overshoot and stabilization time.

The Leeds and Northrup 8694-2 Temperature Potentiometer is constructed with high-quality materials, ensuring robustness and reliability. The bimetallic element is made from nickel-chromium alloy, which is known for its excellent temperature-sensing properties and resistance to corrosion. The potentiometer body is made of brass, and it comes with a stainless steel terminal cover.

This temperature potentiometer is easy to install and use. It comes with a 1/4 inch diameter BNC-type terminal connector that can be used with banana leads or test probes. The potentiometer also has a 1/8 inch diameter threaded hole for mounting, allowing it to be securely attached to a surface.

The Leeds and Northrup 8694-2 Temperature Potentiometer is an essential tool for laboratory and industrial applications where precise temperature sensing is required. Its high accuracy, wide temperature range, and rugged construction make it an excellent choice for a variety of temperature measurement applications.
