I search for Nichrome plate long time, and successfully bought it from Ohmalloy material. OHMALLOY provide real good service in alloy service and can always help me in finding the correct resistance alloy.

—— Mike Harness

OHMALLOY can provie me only 1kg Kovar alloy wire 1.0mm with short time, that is really amazing. Thanks

—— Janey

Really professional in thermocouple wire and cable, what i want just can get from OHMALLOY

—— Chris

Enamelled Constantan 0.08mm, i never expect to get only 2kg of it. But OHMALLOY supply it to me with good quality. God Jesus! Such a reliable supplier from china

Resistance Temperature Detector Cable RTD Wire 2 3 4 Pairs Quick Response

 

 

RTD is the abbreviation of Resistance Temperature Detector, referred to as thermal resistance which resistance changes linearly with temperature.

 

At present, the most common type for RTD are PT100(the resistance is 100Ω when the temperature at 0℃) PT1000(the resistance is 100Ω when the temperature at 0℃) with measuring temperature range: -200℃-800℃

 

The most common type PT100 core is made of copper(Cu100%)with measuring temperature range: -40 ℃-150℃. This type of RTD is widely used in industry by its feature of low cost, high accuracy for wide temperature range, strong stability.

The RTD cable is used to connect the RTD to the measuring device to compensate for errors when the junction point temperature changed.

 

There are three types of RTD cable from the cores:

1. Two Wires Type

Each end of the thermal resistor connected by a wire to extract the resistance signal that is called two-wire type. This lead wire working method is very simple, but with comparatively high resistance which will lead to temperature measuring error, therefore, this wire type is only suitable for occasions with low measurement accuracy.

2. Three Wires Type

One wire is connected to one end of the thermal resistor, and two wires are connected to the other end of thermal resistor. This wire type usually used together with the electrical bridge, which can better eliminate the influence of lead wire resistance. It is widely used in industrial process control.

3. Four Wires Type

Connecting each ends of the thermal resistance by two wires is called four-wire type. Two of the leads provide a constant current (I) for the thermal resistance, converting resistance(R) into a voltage signal (U). At the meantime, the other two wires lead U to the indicator meter. By this way, the four wires type can completely eliminate the influence of the lead resistance. It is mainly used for high-precision temperature detection and measurement.
