PT1000 Simplex Pencil Sensor

A. Product Overview

Pt100 and Pt1000 simplex pencil sensor is a long and slim temperature sensor used for precise temperature measurement in industrial and process applications. The pencil-type design makes it suitable for easy insertion into small openings, pipes, ducts, tanks and machine parts.

The sensor contains one platinum sensing element, which is why it is called a simplex sensor. Pt100 means the sensor has 100 ohms resistance at 0°C, while Pt1000 means the sensor has 1000 ohms resistance at 0°C.

This sensor is commonly used where reliable and accurate temperature measurement is required in liquids, gases, machinery and process equipment.

B. Working Principle

Pt100 and Pt1000 simplex pencil sensors work on the RTD principle. RTD means Resistance Temperature Detector.

Inside the sensor, there is a platinum resistance element. When temperature changes, the resistance of the platinum element also changes. This resistance change is measured by a temperature controller, indicator, transmitter or PLC system and converted into a temperature reading.

For example, a Pt100 sensor gives 100 ohms resistance at 0°C, and a Pt1000 sensor gives 1000 ohms resistance at 0°C. As temperature increases, the resistance increases in a predictable manner. This makes Pt100 and Pt1000 sensors suitable for stable and accurate temperature measurement.

The pencil-style metal probe protects the sensing element and allows the sensor to be inserted directly into the measurement area.

C. Why It Is Used

Pt100 and Pt1000 simplex pencil sensors are used because they provide accurate, stable and repeatable temperature measurement. Their slim pencil design makes them useful in applications where space is limited or where the sensor needs to be inserted into a narrow area.

They are preferred in industrial applications because they offer better accuracy compared to many basic temperature sensors. The stainless steel probe gives mechanical strength, while different cable insulation options help the sensor perform in different temperature and environmental conditions.

This sensor is used to monitor process temperature, machine temperature, liquid temperature, gas temperature and equipment temperature. It helps in improving process control, product quality, safety and equipment performance.
