The DPS-100 Dual Power Sensor
New! The DPS-100 Dual Power Sensor is designed to interface with the above SWP-200 Power Monitor VSWR Protection System. This sensor was developed to meet the demands of today's digital broadcast RF systems. The DPS-100 attaches to any RF directional coupler or DC line section that has been retrofitted with an RF sample element. The RF signals are converted to a pair of proportional precision DC voltages or as an option serial RS-485 data stream. The DPS-100 has two RF ports to measure forward and reflected power. There is provision for an optional temperature sensor, also available from BDI.
There is also provision to monitor a switch closure, such as those used for interlocks. The DPS-100 is supplied with a mounting bracket as shown for attachment to RF rigid line sections. The DPS-100 is suitable for use in measuring analog AM/FM, digital radio/television RF power. RF input is BNC and the output interface is DB9 connector. Connectors also are supplied for temperature and switch closure. Click here for more information.
