COMBINE抯 model MicroSWITCH R2300 radio frequency (RF) point level controller is truly an outstanding value.
It combines rugged construction, quick, easy installation and all the features you need for years of effective, accurate performance.
Operating on the RF impedance sensing principle, the MicroSWITCH R2300 will detect the presence (high level) or absence (low level) of a wide variety of materials. It may be made fail-safe in either high or low mode. It will operate in conjunction with process materials which range from low dielectric (insulating) products such as refined oils, to conductive slurries.
The MicroSWITCH R2300 incorporates COMBINE抯 user-oriented features ... reliability, true coating cancellation capability, explosion-proof/weatherproof enclosures, RFI immunity, heavy duty relays, Easy-On Teflon/316SS probes and our unique 10-Year Warranty.
The MicroSWITCH R2300 has everything you need at a price no higher than the "also rans."
In tens of thousands of installations, spanning more than 90 years of experience, COMBINE process instruments have provided have provided accurate, dependable, long lived service . |
