SD-1 Smart Transmitter Detector Overview
Our SD-1 line of smart transmitters features state-of-the-art gas detectors with a durable flameproof enclosure, providing maximum safety, especially in hydrogen/acetylene atmospheres. A simple magnetic control key is placed over clearly marked positions on the surface plate to test and adjust the instrument without opening the transmitter in situations with a danger of explosion. This “single-man-calibration” is already in use and compatible with other Control Equipment gas detectors, enabling easy maintenance.
