Description
Pencil Type RTD Sensor Pt-100, Simplex 3-Wire, -50 to 450°C, 2.5″ Stem × 6 mm OD, 5 Meter SS Braided Cable
The “Ji” Japsin Instrumentation Pencil Type RTD Sensor Pt-100 is a compact, reliable, and versatile temperature sensing solution designed for accurate temperature measurement across a wide range of industrial, commercial, laboratory, and process applications. This Pt-100 RTD temperature sensor features a simplex 3-wire configuration, a 2.5-inch long stainless-steel stem with 6 mm outside diameter, and a 5-meter stainless-steel braided cable, making it suitable for applications where the sensing point is located away from the temperature indicator, controller, PLC, data acquisition system, or other monitoring equipment.
The sensor is designed for temperature measurement from -50°C to 450°C, providing a broad operating range for monitoring low, ambient, and elevated process temperatures. Its pencil-type construction allows the sensor to be installed in relatively compact spaces where larger temperature probes may not be practical.
Pt-100 RTD Temperature Sensing
The sensing element used in this RTD is Pt-100 (Platinum Resistance Temperature Detector). A Pt-100 sensor has a nominal resistance of 100 ohms at 0°C and changes its electrical resistance predictably with temperature. The measuring instrument determines the temperature by detecting this resistance change.
RTD technology is widely used when stable, repeatable, and dependable temperature measurement is required. Compared with many basic temperature sensing methods, Pt-100 RTDs offer excellent measurement stability and are commonly selected for industrial process monitoring, machinery, HVAC systems, testing equipment, control panels, and general-purpose temperature measurement.
The 3-wire configuration is particularly useful for reducing the influence of lead-wire resistance on the temperature measurement. This makes the sensor suitable for connection with compatible temperature indicators, controllers, transmitters, PLC modules, and other RTD measurement instruments designed for Pt-100 inputs.
Pencil Type Compact Construction
The pencil-type design provides a slim and convenient temperature sensing arrangement. The 2.5-inch-long stem has a 6 mm outside diameter, allowing it to be positioned into suitable thermowells, mounting arrangements, equipment openings, or temperature measurement points where the dimensions are compatible.
The compact stem can be advantageous for applications involving small pipes, vessels, machinery, ducts, process equipment, laboratory setups, and other installations where installation space is limited.
Before installation, users should ensure that the stem dimensions, insertion depth, process conditions, and mounting arrangement are suitable for the intended application.
Wide Temperature Measurement Range
The sensor is specified for a temperature range of -50°C to 450°C. This broad range makes it suitable for numerous temperature monitoring applications, from sub-zero environments to high-temperature industrial processes.
Depending on the application, the sensor can be used for monitoring temperatures in equipment, machinery, heating systems, process lines, ovens, dryers, tanks, panels, and other systems requiring RTD-based temperature measurement.
The actual permissible operating conditions should always be evaluated according to the complete installation, including the sensing element, cable, mounting arrangement, surrounding environment, and connected instrumentation.
5 Meter Stainless-Steel Braided Cable
A key feature of this model is its 5-meter SS braided cable. The extended cable length provides greater flexibility when the sensing location and temperature display or control equipment are positioned some distance apart.
The stainless-steel braided construction provides an additional layer of mechanical protection around the cable, helping make the assembly suitable for demanding industrial environments where cable protection and durability are important considerations.
The 5-meter cable can be useful for installations involving machinery, process equipment, control panels, test benches, HVAC systems, tanks, and other applications where a short sensor lead would be insufficient.
Users should route and secure the cable appropriately during installation and avoid excessive bending, crushing, abrasion, or exposure to conditions beyond the cable’s intended operating capability.
Simplex 3-Wire Configuration
This model uses a simplex 3-wire Pt-100 configuration. A 3-wire RTD arrangement is commonly used in industrial temperature measurement because it can compensate for a significant portion of the resistance introduced by the connecting wires when connected to a compatible three-wire RTD measuring circuit.
Correct wiring is important for obtaining reliable readings. The sensor should be connected according to the terminal identification and wiring requirements of the corresponding temperature indicator, controller, transmitter, PLC input module, or other measuring device.

Installation & Usage
For accurate temperature measurement, the sensor should be installed so that the sensing portion is adequately exposed to the temperature being measured. The probe should be positioned at a representative measurement point and secured properly.
Connect the three wires to a compatible Pt-100 input according to the wiring configuration specified by the measuring instrument manufacturer. Incorrect wiring or an incompatible input configuration can result in inaccurate readings.
During installation, avoid excessive mechanical stress on the probe and cable. The stainless-steel braided cable should be routed safely and protected from sharp edges, excessive heat, moving machinery, and conditions outside its intended application.
