Keller Company Pressure Sensor Series 35XHTC / 35HTCX
High-temperature pressure sensor that can be used up to 300℃, achieving ±0.5% accuracy at 300℃!
The high-temperature pressure sensor 35XHTC can be used for media temperatures up to 300°C. It is significantly different from the commonly available pressure sensors that can simply be used at high temperatures, as it achieves high accuracy of ±0.5% full scale (FS) even at a media temperature of 300°C through a mathematical correction method. In addition to a digital RS485 interface, analog current or voltage outputs are available, and scaling settings can be configured via the digital signal. The pressure connection is standard G1/2 male thread (flush diaphragm). *From 2025, the model name will change to 35HTCX. 【Features】 • Can be used at media temperatures up to 300°C, achieving ±0.5% accuracy at 300°C • Standard dual outputs of digital RS485 and analog output • Analog output range can be changed via digital RS485 (turndown) • Excellent long-term stability • Cooling capillary tube structure
