Learn more about Temperature and humidity sensor Selectric STP-S1
STP-S1 is a wireless temperature and humidity sensor designed to monitor the condition of live connections, power buses, switches, switchgear, and other electrical equipment. Data is transmitted via the industrial LoRa radio protocol to the industrial STP-IG gateway without the need to run additional signal cables. The sensor is intended for use in distribution networks with a voltage up to and including 110 kV.
Advantages
The sensor includes:
- a built‑in NTC temperature sensor;
- a built‑in humidity sensor;
- a LoRa radio module;
- a self‑contained power supply system;
- an industrial‑grade housing;
- a mounting system for current‑carrying parts.
Power is supplied:
- from the magnetic field of the current‑carrying parts;
- or from a built‑in battery.
This allows the sensor to be installed without additional power supply and cable routing.
Quick and convenient installation.
Mounting is carried out:
- magnetic tape;
- fixing plates;
- 3M tape;
- cable clamp.
Installation does not require drilling, equipment modifications, or the laying of additional cables.
Application
STP-S1 is used for continuous monitoring:
- contact connections;
- power buses;
- cable connections;
- circuit breakers;
- KRU and KSO cells;
- transformers;
- MCC draw‑out elements;
- LV and HV switchgear;
- live parts of substation equipment.
