Features
Industry Applications
|
| The RKI ECLIPSE™ model is a unique single gas non-intrusive calibration (NIC) smart transmitter for LEL combustibles, Oxygen, Hydrogen Sulfide, or Carbon Monoxide. The ECLIPSE™ is microprocessor controlled, simple to install and operate, requires no tools or magnets to operate and has no moving parts. It utilizes a patent pending eclipse type technique for accessing the zero and calibration modes. The zero and calibration functions are performed by placing your finger over a special optical sensor built into the transmitters the optical sensor is covered (eclipsed) in a designated security sequence, then the zero and calibration controls are activated. The ECLIPSE™ automatically compensates for background light changes in the area. The housing of the ECLIPSE™ never needs to be opened, which allows for simple calibration without the effort of declassifying the area. It is designed so that a complete field calibration can be performed by one person. The stainless steel flame arrestor housing that covers the sensor is water repellent with a special patented water resistant coat-ing. The transmitter provides a 4-20 mA output which is powered by a 24 VDC power input. The ECLIPSE™ represents the latest leading edge technology in sensor / transmitters today. |

Optical Sensor Technique:
RKI Instruments has revolutionized NIC style transmitter designs with the ECLIPSE™.
Utilizing a new patent pending optical sensor technique, the ECLIPSE™ can access the zero and calibration modes without opening its explosion proof housing. The ECLIPSE™ requires no magnets, special tools, or I. R.transmitters to operate, and has no moving parts. Simply place your finger over the “optical sensor” in a special sequence to access and activate the calibration and zero modes. This pre-defined access sequence provides a security feature against unauthorized personnel as well as preventing accidental entry into these service modes.
The ECLIPSE™ is also designed with a special safeguard, making it impossible to adjust span levels without applying actual span gas.
