Ramsey Microwave Point Level Detector - Thermo Scientific - Process Systems - #1

Text version of the page

Product Specifications The Thermo Scientific Ramsey Microwave Point Level Detector is a reliable instrument that can see through non-metallic wall build-up and detect the presence or absence of any material. By detecting the conditions in your chutes, it will alert you of any problems or disruptions in your process, allowing you to efficiently rectify the situation. This will save Thermo Scientific you time and money. Ramsey Microwave Point Level Detector Non-Contacting Chute Detection The Thermo Scientific Ramsey Microwave Point Level Detector is a totally noncontacting instrument with a range from 10 cm (4 in) minimum to 150 m (492 ft) maximum. These reliable units can see through non-metallic wall build-up and detect the presence or absence of any material. The switch can be used in pressurized coal down comers; electro-static precipitator hoppers; and in fly ash, clinker and coal transfer chutes. It provides high and low point level detection. High temperature applications are not a problem for the RamseyTM Microwave Point Level Detector. Each unit is protected from the process by a polyethylene, ceramic or tempered safety sight glass window. The switch is a safe and environment-friendly replacement for nucleonic switches and is not restricted by OSHA or FCC regulations. Theory of Operation The Thermo Scientific Ramsey Remote Microwave System (RMS) is a microwave pulse sender-receiver system comprised of three electrically isolated units: the sender, the receiver, and the amplifier. The sender-receiver units are mounted in-line and face each other. The Thermo Scientific Ramsey Integral Microwave System (IMS) is a microwave pulse sender-receiver system comprised of two electrically isolated units in an integral housing: the sender and the receiver/amplifier. The sender-receiver units are mounted in-line and face each other. The sender emits a burst of microwave energy toward the receiver. Each burst occurs 200 times per second. When the line of sight is clear, the receiver will detect each of these bursts. If the line of sight is interrupted by sufficiently reflective or absorbent material, the receiver will not detect the microwave energy. The receiver is designed to switch a relay when its detector changes. Settings for sensitivity and time delays allow the user to customize the control to their specific application.
