Product Attributes

Introduction

HD421 is a Pt temperature sensor compliant with DIN EN 60751, covering a temperature range of -70 °C to +850 °C. It features a wide operating window up to 850 °C, high accuracy across a broad temperature range, strong resistance to vibration and shock, and is suitable for soldering and brazing. The sensor is characterized by long-term stability, accuracy across a wide temperature range, and broad compatibility. It is used for high-temperature process monitoring in energy and power generation, petrochemical, and related industries, and is also applicable in principle to automotive applications. The nominal resistance measurement point is located 4 mm from the end of the sensor body.
