Gas sensor KSIM 1260 for detection of Sulfur Hexafluoride SF6


KSIM 1260 Sulfur Hexafluoride SF6 Sensor Mode of operation
The KSIM 1260 is a high quality infra red Sulfur Hexafluoride gas detector designed to operate with KIMESSA or third party control panels.


The infra red sensor technology is diffusion based and Sulfur Hexafluoride specific, housed in a robust metallic enclosure and designed for one-person calibration.


The versatile KSIM 1260 outputs allow for user selection of 0-20mA, 4-20mA, 0-10Vdc and digital BUS. The BUS option is used in conjunction with the addressable KIMESSA CANline-32-channel gas monitor panel, incorporating data logging and multi-optional programming capability. The SF6-detector is available with a linearised measuring range from 0…1000 ppm (0.1 Vol. %) up to 0…5.0 Vol. % and its output signal is temperature compensated from -30℃to +70℃.


A novel feature on the KSIM 1260 facilitates direct measurement of the gas level via a 3.5mm jack connection, enhancing the overall flexibility of the SF 6 sensor.


The KSIM 1260 is also designed for use with a hand held optical calibration tool called the CRC–Calibration Remote Control, permitting calibration of remote SF 6 sensors.
