Description
Plastic Head PT1000 RTD Sensor (Model APPS-6×200) is a cost-effective PT1000 resistance temperature detector (RTD) designed for reliable temperature measurement in industrial process control, HVAC, OEM machinery, and automation applications. Featuring a Simplex PT1000 sensing element, corrosion-resistant SS316 stainless steel sheath, compacted MgO mineral insulation, an adjustable 1/2-inch BSP process connection, and a lightweight plastic terminal head, this industrial temperature sensor delivers dependable performance across a wide operating range of -50°C to +400°C. The PT1000 element, with its nominal resistance of 1000 Ω at 0°C, offers excellent compatibility with PT1000-based instrumentation and can help reduce the proportional influence of lead-wire resistance in suitable installations.
Designed for general industrial applications in non-hazardous areas, the adjustable BSP fitting allows the insertion depth to be set during installation for tanks, pipelines, vessels, and process equipment. The durable plastic terminal head protects field wiring while providing an economical alternative to metal terminal heads for standard industrial environments. Manufactured by Aavad Instrument, this PT1000 RTD sensor with plastic head is ideal for process automation, machinery temperature monitoring, utilities, HVAC systems, manufacturing plants, laboratories, and OEM equipment requiring reliable and cost-effective PT1000 temperature measurement.

FAQs
1. What is a Plastic Head RTD Sensor and when should you choose it over a Metal Head?
A Plastic Head RTD Sensor is a PT1000 Resistance Temperature Detector (RTD) that uses a lightweight polymer terminal head instead of a die-cast aluminum head. Aavad’s Model APPS-6×200 is a simplex PT1000 RTD Sensor with an SS316 stainless steel sheath and an operating temperature range of -50°C to +400°C. It is a cost-effective solution for general industrial temperature measurement in non-hazardous environments.
2. Does the Plastic Head reduce the Sensor’s durability or accuracy?
No. The PT1000 sensing element, SS316 sheath, and compacted Magnesium Oxide (MgO) insulation are identical to those used in metal-head RTD sensors. The only difference is the terminal head material. The plastic head provides reliable protection against dust, humidity, and water splashes while offering a more economical solution for non-hazardous industrial applications.
3. What is the Process Connection of the Plastic Head RTD Sensor?
The sensor features an adjustable 1/2″ BSP (Male) process connection, allowing the probe insertion depth to be adjusted during installation for tanks, pipelines, vessels, and process equipment. It also includes a single cable entry and a nickel-plated ceramic terminal block for dependable electrical connections.
4. Why is PT1000 a good match for a budget-friendly Plastic Head Sensor?
A PT1000 RTD has a higher resistance than a PT100 sensor, which significantly reduces the effect of lead-wire resistance, especially in 2-wire installations and long cable runs. Combining a PT1000 sensing element with a cost-effective plastic terminal head provides reliable temperature measurement while reducing overall installation and equipment costs.
5. Where is the Plastic Head PT1000 RTD Sensor typically used?
Plastic Head PT1000 RTD Sensors are widely used for industrial temperature monitoring, commercial HVAC systems, building management systems, pipelines, storage tanks, OEM machinery, pump bearings, gearboxes, hydraulic power packs, and industrial automation in non-hazardous environments where economical and reliable temperature sensing is required.
