Fixed Combustible Gas Detector Head – GD-D58 & SD-D58

Features:

• Explosion proof design
• CE approved
• Diverse flammable gas vapour detectable
• Long life sensor and sampling pump
• Various sampling accessories
• Plug-in sensor replacement and easy maintenance

Application/s:

• LPG, LNG utilities
• Petro-refinery, Petrochemical plants
• Chemical plants
• Iron and steel works
• Engineering, public works
• Power station

Overview:

Our SD-D58 line of smart transmitters feature state-of-the-art gas detectors with durable flameproof enclosure, best operability and maximum safety, especially in hydrogen/acethylene atmospheres. A simple magnetic control key is placed over clear marked positions on the surface plate to test and adjust the instrument without opening the transmitter in situations with danger of explosion.

This “single-man-calibration” is already in use and appreciated with other RKI gas detectors for easy maintenance. The built-in microprocessor features a self diagnosis functions and automatic zero setting to minimise maintenance work and costs compared to other detectors. Dual alarm contacts or trouble alarm contact are provided for activation of external buzzer or alarm light. Powered by 24VDC, the unit has a 4-20mA output for communication to outside controllers, for external readouts or alarming devices.
