Reliable Optical Communication for Smart Metering
Modern AMI systems require stable and accurate data capture at the meter level. Manual meter reading was time-consuming and error-prone.
Tespro's optical probes, including the TP-BT and USB series, enabled automatic data retrieval via optical ports, supporting various meter brands and protocols. Bluetooth and USB models offered flexibility for both field and desktop use.
Case
Product Case
A metering service company faced frustrations with incompatible probes during on-site meter verification—existing tools failed to match the dedicated connectors of PRS1.3/PWS1.3 instruments, requiring cumbersome adapters that compromised data accuracy for electricity and thermal meter tests.
Tespro’s TP-16 Calibration Optical Probe resolved this with its custom-matched Lemo connectors for PRS1.3 and PWS1.3 devices, enabling direct, stable connections without extra adapters. Its ability to sense both light and IR pulses ensured reliable conversion to electric pulses for precise energy data capture.
Strong magnetic adhesion and the optional TP-GS2 fixture allowed secure mounting on any meter type, while the durable ABS+PC housing stood up to frequent field use. This simplified the verification workflow, ensuring consistent, hassle-free energy data collection for quality checks.
