LABFACILITY DM-311 Platinum RTD Sensor, 1 kohm, -50 to 500°C

The LABFACILITY DM-311 is a high-precision thin-film platinum sensing resistor designed for demanding temperature measurement applications. This compact and robust RTD sensor offers excellent stability and rapid thermal response, making it suitable for a wide range of surface and immersion sensing tasks where the element can be suitably protected.

Constructed with vibration-resistant Pt100 sensor elements, the DM-311 is approved to the stringent IEC751 Class A, B, and 1/3DIN standards, guaranteeing exceptional accuracy and reliability. It operates across an impressive temperature range from -50°C to +500°C, providing versatility for both industrial and laboratory environments. The sensor features a nominal resistance of 1 kohm at 0°C and exhibits minimal self-heating of less than 0.5°C per milliwatt, ensuring measurements are not skewed by the sensor's own operation.

With a remarkably fast thermal response time of 0.1 seconds, this RTD sensor can track temperature changes almost instantaneously. Its long-term stability is rated at ±0.05%, ensuring consistent and dependable readings over its operational lifespan. The fundamental interval accuracy between 0°C and 100°C is exceptionally tight, contributing to its high-performance credentials.

This component-with-leads style sensor is ideal for integration into custom sensing assemblies and instrumentation. Its thin-film platinum construction provides a durable and accurate sensing solution that stands up to challenging conditions, including environments with vibration.
