TRwS x2y Sensor series

After successful TRwS x14 and x15 series, the new TRwS x24 and x25 series comes with many improvements. Weighing system with precise electronic design is an excellent tool to measure all types of precipitation within wide temperature range, harsh wind and snow conditions.

TRwS is the most sensitive and very accurate rain gauge. Simple mechanical construction together with very sophisticated firmware can guarantee perfect performance. TRwS is available with collecting areas of 200cm2, 400cm2 and 500cm2.

Main features Power supply – two modification of power supply are available: 3V and 5-30V. Low power supple is suitable for IOT systems powered by primary battery cells and extended range of power supply for existing systems. Communication protocols – SDI 12 ver.1.4 was implemented and fully compatible with previous versions. RS 485 – MODBUS and MPS protocol is available. Register organisation – all parameters, data, values are organised register philosophy. Table with registers and descriptions is available to customer for easy implementation to their systems. Implemented algorithm gives several sets of data: measured, corrected and optional.

Measured data:
  • one minute, 15 minutes, total , any time period precipitation
  • 10 sec rain intensity express in mm/hour
  • corrected data – evaporation, loses on the surface, wind influence
  • Monitoring of power supply – Ubat, Ibat, U solar ..
  • many diagnostics data
Bluetooth communication between TRwS and handheld mobile – Android and IPhone also. Comfortable service work without need cable connection with sensor. APP allow to check functionality, accuracy, valuation, settings several parameters, FW upgrade in situ. Options as ambient temperature measurement, wind shield Options Heating 60W: / 2.5A @ 24V • Wind Shield: Tretyakov • Ambient Air Temperature: Pt1000 Applications Hydrology • Meteorology • Environment • Agriculture App: MPS system AiO Bluetooth application Scan for nearby compatible sensors.
