The Rodgers & Roberts Shaw PG9A42JTL20 Electro-Heat 750mV Thermopile is a high-performance temperature sensor designed for various industrial applications. This thermopile features 36 leads, making it suitable for use in thermocouple circuits where greater accuracy is required.
This thermopile is constructed using 36 individual junctions, each made up of a pair of dissimilar metals. When a temperature difference exists between the hot and cold junctions, an electrical voltage is generated. The 750mV output voltage of this thermopile is ideal for use with low-voltage temperature measurement instruments.
The PG9A42JTL20 thermopile is designed to operate in harsh environments, with a temperature range of -20 C to 600 C (-4 F to 1112 F). It is made from high-quality materials that ensure excellent thermal conductivity and stability, resulting in precise and reliable temperature measurements.
The thermopile is compact in size, measuring only 1.1 inches in length and 0.4 inches in width, making it easy to install and integrate into various industrial systems. It is also resistant to vibration, shock, and corrosion, making it a durable and long-lasting solution for temperature measurement applications.
This Rodgers & Roberts Shaw thermopile comes with a protective sheath to prevent damage to the leads during installation and use. It also comes with a certificate of calibration, ensuring that the thermopile meets the required accuracy specifications for your application.
Overall, the PG9A42JTL20 Electro-Heat 750mV Thermopile is an excellent choice for those seeking a high-precision temperature sensor for industrial applications. Its robust design, wide temperature range, and reliable output make it a versatile and valuable addition to any industrial measurement system.
