Distinctive features:
STP-S3 — a wireless temperature and humidity sensor with three external NTC temperature channels. The device is designed to monitor the condition of live connections, power buses, switches, distribution devices 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 designed for operation in distribution networks with a voltage of up to and including 1000 V.
Advantages:
Temperature control at three points.
STP-S3 has:
- 3 independent inputs for connecting external NTC sensors;
- simultaneous control of three phases or three separate connections.
Various types of NTC sensors can be used for connection:
- a sensor made of ABS plastic with a connecting wire length ranging from 0.4 m to 1 m.
- a sensor with a ring connector with a diameter ranging from 4 mm to 10 mm
The sensor includes:
- an STP-S3 unit
- 3 inputs for NTC sensors;
- a built‑in humidity sensor;
- a LoRa radio module;
- autonomous power supply system;
- industrial design housing;
- mounting system for live parts.
Meals are provided:
- from the magnetic field of the live parts;
- or from the built-in battery.
This allows the sensor to be installed without additional power or cables.
Quick and convenient installation.
Fastening is carried out:
- magnetic tape;
- fixing pads;
- 3M tape;
- cable clamp.
Installation does not require drilling, equipment modifications, or laying additional cables.
Application.
STP-S3 is used for monitoring:
- simultaneously three phases of the busbar;
- contacts of circuit breakers;
- bolted connections;
- power tires;
- cable lugs;
- transformer inputs;
- switchgear;
- MCC cabinets;
- BRNO engine.
