Available with Hazardous Certifications

These certifications allow global OEMs to standardize across multiple markets and applications without redesigning or recertifying sensor configurations: IECEx (Worldwide), SIL2 (Worldwide), ATEX (Europe), CSA (USA/Canada), KCs (Korea), PESO (India), CCC (China).

Designed to Fit Your System

Minco understands that no two systems are alike. That’s why the Rotating Bolt Temperature Sensor is available in multiple configurations to fit your exact needs:

Thread options: 1/4-20 or M6 x 1
Temperature range: –50°C to +260°C (depending on configuration)
Sensing elements: Nickel or Platinum RTDs with multiple tolerance classes
Leadwire options: PTFE, PTFE with stainless-steel braid and/or FEP jacket covering or stainless-steel braid with FEP jacket and elastomer fill.
Custom lead lengths and termination methods available

Optional features like stainless-steel feedthroughs prevent oil seepage when used with pressure seal fittings, making the sensor a smart choice for sealed or fluid-exposed assemblies.

Key Advantages:

Independent cable rotation — prevents wire twisting and simplifies installation

PT100 vs PT1000 RTDs: What’s the Difference and Which Should You Choose?

J Lanners — Tue, 03 Jun 2025 13:27:47 +0000

When it comes to industrial temperature measurement, RTD temperature sensors (Resistance Temperature Detectors) are a go-to choice for engineers and designers seeking accuracy, stability, and reliability. Among the most common RTDs are the Platinum RTDs. Within this family, the PT100 and PT1000 are the most common resistance values. Both are known for their precision and long-term stability. But what’s the real difference between them? And when should you choose one over the other?

Let’s break it down.

What Is a PT100 and PT1000 RTD?

Both PT100 and PT1000 RTDs use platinum as the sensing element, known for their consistent temperature-resistance relationship. Both have Temperature Coefficient of Resistance (TCR) values of 0.00385 Ω/Ω/°C. The key electrical difference lies in their nominal resistance at 0°C:

PT100 RTD: 100 ohms at 0°C

PT1000 RTD: 1000 ohms at 0°C

This factor influences how the sensor behaves in terms of sensitivity, power, wiring, and electrical noise.

Key Differences: PT100 RTD vs PT1000 RTD

Feature	PT100	PT1000
Resistance at 0°C	100 ohms	1000 ohms
Resistance Sensitivity	Resistance Change: 0.39 ohms/°C	Higher resistance output for same temp change, 10x the PT100 (3.9 ohms/°C)
Voltage Sensitivity	Nominal change in voltage for a given measuring current and temperature delta	10x voltage change with the same current and temperatures
Power Consumption	Nominal Power Consumption	Requires less current for given voltage change, thus lower power consumption
Wiring Effects	More susceptible to lead wire resistance errors, especially with 2-wire circuit configurations.	Less susceptible, better suited for 2–wire circuits. See further comments below.
Electrical Noise Effects	Larger induced noise signals and greater amplification of the induced noise	Picks up less of the noise signal, and amplification effect 1/10th that of PT100
Cost	Nominal	Slightly to significantly higher, depending on element construction

Wiring and Signal Accuracy

In 2-wire configurations, PT100 sensors can suffer from lead wire resistance, which can skew the reading. That’s why 3-wire or 4-wire PT100 RTDs are common in high-precision applications—they help compensate for lead wire effects.

On the other hand, a PT1000 RTD, with its higher resistance, experiences less relative error from the same lead wire resistance. This makes it ideal for long-distance installations or 2-wire configurations where simplicity and reduced wiring cost are priorities.

Applications and Use Cases

Aerospace and defense: High-reliability temperature sensing in mission-critical systems

Automotive: Engine and battery temperature monitoring

Energy and power generation: Turbines, generators, and motors

HVAC systems: Energy-efficient heating and cooling controls

Industrial automation: High-accuracy machine control

Medical devices: Patient warming and sterilization equipment

Process control: Chemical, pharmaceutical, and food processing industries

So, which RTD is right for your application?

Choose PT100 when you need high accuracy and are using a 3-wire or 4-wire configuration, which helps compensate for lead wire resistance. PT100s are widely supported and ideal for systems where power consumption and wiring length are less of a concern.

At Minco, we specialize in precision RTD temperature sensors tailored to your industry’s toughest challenges—from aerospace and medical to HVAC and renewable energy. Whether you need a custom-engineered PT100 probe or a rugged PT1000 sensor for remote environments, our solutions deliver accuracy, durability, and performance.
