Power Detector

Microwave PLC 4-20 Power Meter- CellencorCellencor proudly offers an accurate, rugged, and compact power detector that quickly and easily converts coaxial RF signal to a 0-5V or 4-20 mA output allowing you to precisely monitor the microwave power being applied during your process. The detector can accurately detect RF over a large frequency range of 50 MHz to 3.8 GHz. This small box, roughly 3.2x2.4x1.3", has a dynamic input range of -22 to 38 dBm in 50 Ω impedance. Our detector is a true-RMS detector, meaning that it will give you accurate readings for various waveforms where averaged meters would not. This power detector comes with a Male N-connector to securely connect directly to directional couplers. It can also easily attach to an SMA connection using an adapter.


Our power detector also comes with a 30”- 5 strand M12 female connector cable to easily run from the point of measurement to a PLC. This makes it very simple to hook the power detector up to an input card on most industrial PLCs. The power detector can be powered using 9-24V DC. The unit is designed to be durable and robust in order to stand up to the conditions in even the harshest of industrial environments. It is water resistant as well as drop and shock proof. It is constructed from a beautiful, one piece, extruded, anodized aluminum case as well as premium, top shelf PCB components. Our detector box is also very energy efficient, drawing <50mA during normal use. Our low cost precision detector is a great choice for many power monitoring needs.
