How to buy

  • Description

    STE2 r2 can connect up to 5 Sensors (5 sensor values) via 2x RJ11 port (1-Wire & 1-Wire UNI) and up to 2 Detectors via DI (Digital Inputs) for dry contacts.

    A built-in web server is used for device configuration. STE2 r2 is a device with SNMP support designated for remote monitoring Temperature, Relative Humidity and other external sensors.

    Device can be connected via Ethernet or WiFi. When the measured temperature (humidity, voltage, ..) on the external sensor(s) exceeds the defined Min-Max range (Safe Range), STE2 r2 sends an email alert (SMS, Voice Call, ..). In device configuration is Alarms tab, where you can define up to 3 sets of targets and assign them to individual sensors.

    STE2 r2 is Standalone Monitoring device, means the device can be fully configured via the web, can send emails itself (SMTP server), supports SNMP, etc.
    Connection of the product to the Portal (SensDesk technology) is not enabled by default. The portal have to be manually activated as a functional extension (central device management, data history, SMS and Voice Call alerts).

    Detect system overloads, loose defective components and damaged switchgear. Infrared electrical testing finds hot, dangerous problems quickly. Infrared electrical inspections find hot spots caused by defects in connections and components.

    Infrared thermography is used to find areas of excess heat (caused by increased resistance) so that problems can be corrected before a component fails, causing damage to the component, creating safety hazards and productivity loss. Because increased heating is a sign of failure, infrared is the best diagnostic tool available for finding these hot connections in the early stages of degeneration.
