Industrial Solution
Our wireless PSI monitoring system is engineered to meet many industrial, commercial, and OEM temperature measurement applications. The all stainless steel, welded, thin film sensing element provides very fast response time and is compatible with many different media sensing applications. With a robust design resistant to vibration, shock, and EMI/RFI, the sensor provides high accuracy over a wide compensated temperature range.

Applications include:

  • Reach-in Refrigerators and Freezers
  • Walk-in Refrigerators and Freezers
  • Refrigerated Prep Tables
  • Undercounter Refrigerators
  • Refrigerated Merchandisers
  • Bar Refrigeration
  • Industrial Fridges
  • Industrial Freezers
  • Chest freezers
  • Ovens
  • Dishwashers

Using the 4-20mA bridge unit from Aretas, you can breathe new life into existing infrastructure and capitalize on the abundance of high quality industrial 4-20mA sensors already on the market. Coupled with the Aretas Control System you can also take inputs from 4-20mA systems and control 3 output channels on a separate controller board.

Additional 4-20 mA wireless industrial sensors include:

  • High pressure air system monitoring (from 0-100inWC to 0-5000 PSI)
  • Ultrasonic proximity detection
  • Flow metering
  • Tank level sensors, level sensing, float level, etc
  • Air velocity measurement / air flow measurement

Real time data can also be viewed locally from a PC with the Aretas real time reporting software. Optional monochromatic LED displays are also available for viewing instantaneous data on the 4-20mA unit. Currently, two 4-20mA devices are supported per unit. 10 channel, ultra high precision units are also available for custom order.
