This code is sent to the receiver via FM radio transmission. There, the original analog signal is reconstructed and a scaled output signal is produced. The built-in UHF radio transmitter and receiver circuits operate on 916 MHz and are type approved, allowing license-free use. A fixed, 1 compact, ⁄4 wave helical antenna on both transmitter and receiver units enables line-of-sight operating ranges from up to 200 yards. **Applications Difficult-to-Wire Installations Remote Monitoring of Strain Gages Remote Stress Analysis Weighing Systems Remote Pressure Monitoring** The compact design incorporates miniature microprocessor-based circuitry, which provides 16-bit analog-to-digital conversion and digital encoding for the radio transmission. Owing to highly reliable designs and data errordetection techniques, data transmission is safe and free from errors caused by interference. ## **An Innovative Solution** In difficult installations, OMEGA’s remote telemetry system for mV sensors provides an innovative alternative to costly cables or wires. The transmitter and receiver units are powered by rechargeable batteries. Battery life can be extended up to 500 hours by The RT400 system enables remote data acquisition from sensors, without hard-wiring. using duty-cycle power saving (a 1000 Ω load sampled every 10 seconds). Both the transmitter and receiver units are lightweight and housed in a rugged ABS case that provides environmental protection against water or dust to IP65 standards. An 8-way DIP switch sets the transmitter and receiver address codes. The 8-bit address code prevents interference from adjacent sets, and up to 256 codes are available. The RT400 transmitter will interface directly with a Wheatstone bridge sensor. An excitation voltage of 3.3 Vdc powers the sensor. The excitation signal goes on 60 ms before the sensor output is sampled, then switches off to extend battery life. Bridge sensitivities from ±2 mV/V to ±400 mV/V are available for maximum sampling sensitivity. In reconstructing the signal from the transmitter, the RT400 receiver produces a scaled output of 0 to ±2.5 Vdc. **C-43** **C** ## **RANGES OF UP TO 200 YARDS** ## **SPECIFICATIONS RT400T TRANSMITTER** **DP25B-E, process meter, $245, see page D-23 for details.** **Frequency Range:** 916 or 433 MHz **Transmitter Power:** <10 mW **Transmission Interval:** 500 ms to 10 s adjustable **Address ID:** 0 to 255, switch selectable **User-Selectable Input Ranges:** **RT400R, receiver, $425, shown smaller than actual size.** ±2 mV/V ±5 mV ±10 mV/V ±25 mV ±200 mV/V ±500 mV ±400 mV/V ±1000 mV **Resolution:** >0.02% (13-bit) **Sensor Excitation:** 3.3 Vdc **Power Requirement:** Internal 3.6 Vdc @ 120 mAh rechargeable battery **Standby Current:** 150 µA **Battery Life:** 500 hr typical when fully charged **Connects to 4 mA display Dimensions:** 42 **mm (in)** (1.7) 90 (3.5) 21 (0.8) ~~eS~~ 55 (2.2) ~~I~~ 40 (1.6) **AVAILABLE FOR FAST DELIVERY!** **To Order (Specify Model Number) MODEL NO.
