The RKI “S” series gas sensor/transmitters are highly reliable and very cost effective basic 4-20 mA transmitters for detection of common gas hazards. The “S” series transmitters are available for LEL, Oxygen, H2S, CO, or for 0 - 500 ppm Hydrocarbon detection (for various fuels or solvents). The electronics are encased inside a potted package to avoid damage from mechanical abuse or corrosion, and the amplifier is installed inside an explosion-proof enclosure. Sensors for LEL, H2S, CO, and ppm HC are explosion-proof with flame arrestors. The Oxygen sensor utilizes an internal I.S. barrier, so all 5 versions are designed for use in hazardous atmospheres.
The only tools required to calibrate the “S” series are a voltmeter, screwdriver, and cal gas. The zero and calibration functions are performed by adjusting potentiometers on the amplifiers. The amplifier has test jacks for connection of a voltmeter for calibration purposes, and the sensor response is viewed on the voltmeter as a 100mV to 500mV signal. Field calibration can be performed easily and quickly by one person.
The “S” series transmitters can be used either indoors or outdoors. The flame arrestors utilize a patented coating which makes them water repellent, and splash guards are also available for use in very wet environments.
The transmitter operates from 24 VDC (10.5VDC to 30 VDC), and provides a 4-20mAsignal which can be connected to a wide variety of controllers. |
