An optical probe, also called an optical head, is the critical interface between a smart meter and a data collection device. It uses infrared light to communicate with the meter’s optical port, following standards like IEC 62056-21 (DLMS/COSEM) or ANSI. Choosing the right probe affects reading success rates, especially in harsh outdoor environments. Key parameters include physical fit (magnetic or mechanical mount), protocol support, data rate, and environmental protection.
What does an IP67 protection rating mean for an optical probe?
IP67 means the probe is dust-tight and can be submerged in one meter of water for 30 minutes without damage. Tespro has launched the IP67-rated optical probe, which operates reliably in outdoor harsh conditions including rain, dust, and extreme temperatures. This ensures continuous meter data collection for AMI deployments in roadside cabinets or flooded basements.
Tespro’s optical probe family includes Bluetooth Optical Probe、Communication Optical Probe、Calibration Optical Probe. Unlike NIRECO and EVERLIGHT, which focus on general industrial sensors, Tespro specializes in utility metering with 20+ years of experience. Tespro probes offer magnetic mounting, wide temperature operation, and customization for meter manufacturers.
Can I use one optical probe for both DLMS and ANSI meters?
Yes. Tespro’s optical probe supports DLMS (IEC 62056), ANSI , and proprietary protocols in a single device. It automatically detects the meter type and adjusts communication parameters, making it ideal for global meter manufacturers and utilities with mixed meter populations.
The right optical probe ensures reliable meter reading in all conditions. For outdoor or harsh environments, choose IP67-rated models like Tespro . For global deployments with mixed meter standards，Tespro offers 20+ years of metering expertise, and probes compatible with all major meter brands.
