Power Quality Meter

The LTE-M power quality meter is a device developed for monitoring of low voltage grids and transformers. The device has been developed with an eye on modularity and low- cost so that it can be used for any application,
at any location and it is cost-effectively scalable. Via the Modbus protocol extensions can be coupled to the main module to measure additional low voltage fields, transformer temperatures, ambient temperatures, door contacts, short-circuit protection relays, public lighting and much more. In addition, existing
Modbus equipment can also be connected. These capabilities make this device suitable for mobile measurement solution to complete distribution automation.

Indoor climate sensor

Temperature and humidity measurements are the most performed measurements these days. Both quantities play an important role in many situations and business processes. Temperature and humidity have a direct effect on employee performance and the life of equipment & goods. Thanks to Crest Sensors, measuring the indoor climate is a piece of cake. The indoor climate sensor offers the possibility to measure the temperature and humidity in every conceivable location, including basements. With the supplied magnectic tape and microsuction tape, the sensor can be mounted on stone walls and metal surfaces. With the included battery, a battery life of up to 10 year can be achieved.

Universal RTU

Many assets in the field are located in hard-to-reach locations and whether or not have a mains power connection. To be able to digitize these assets and unlock the data to an online environment for monitoring, Crest Sensors
developed the universal RTU. This waterproof sensor is battery powered (internal or external) and can handle up to measure and forward 5 different input signals via 4G NB-IoT. The sensor has a modular construction so that he can read every possible sensor. The RTU is plug and play reducing installation time
to remain very limited and new sensors can be easily linked. Through downlinks the software can be updated or settings such as alarms and measure / send intervals can be easily adjusted.

  • Analog & digital sensors (0-10V / 4-20mA / IO / Modbus / Mbus / Canbus / SPI / I2C)

  • Up to 5 inputs (customazible)

  • 4G NB-IoT cellular connectivity

  • Battery powered (up to 10 years)

  • Internal battery or external battery pack

  • Fall detection (movement in xyz axis)

  • Send button

  • Secure data (end-to-end encryption)

  • Firmware updates over the air (FOTA)

  • Configurable alarm values

  • Configurable send interval

  • Easy mounting

  • Plug & Play

  • Low-cost

  • IP67 (IP68 on request)

Dinrail RTU

For the more challenging IoT applications where more sensors must be read real-time, Crest Sensors has developed the dinrail RTU. This module features 4G LTE-M connectivity over which the data can be sent directly to an online environment. In addition, the module has a display on which the current data is visible and settings can be adjusted via the menu. The module is sold seperately or is available as a complete solution. The complete solution consists of a watertight box containing the RTU, a 12V backup battery and a battery charger. This system can run on 230V AC or solar energy. Due to the modular design, the dinrail RTU can be connected to any system. The module has 10 input connections available.

  • Analog & digital sensors (0-10V / 4-20mA / IO / Modbus / Mbus / Canbus / SPI / I2C)
