Wireless Transceiver Derives Power From The Loop

Relying on unique nanotechnology and an ASIC, the LPT wireless transmitter extracts the loop’s current, 4 to 20 mA or 10 to 50 mA, to charge a super capacitor to power its RF transmitter. Importantly, this technique does not affect the accuracy of the loop. A microcontroller monitors the input current loop and the capacitor’s energy charge to determine the frequency of transmission, slower at 4 mA and faster at 20 mA. The receiver section, externally powered with 12 to 28 Vdc, converts RF from binary to a 4 to 20 mA, or 1V to 5V, output. The LPT employs an internal lithium battery for emergency transmissions or when the loop is at a low for long periods of time. Single-unit price is $500. OTEK CORP., Tucson, AZ. (877) 227-6835.
