Immersion Temperature Sensor

Description

The Ace Instruments immersion type temperature sensors feature options of RTD Pt100, RTD Pt1000, or NTC thermistors. Designed with versatility in mind, the AI-200-T series features optional stainless steel thermowells, allowing users to measure water or fluid temperatures in HVAC systems or any pipeline application with selectable thermowell length to ensure accurate temperature readings. Each probe provides superior heat transmission, quick reaction times, and the thermowells offer protection from moisture.

Applications

• Data Center Cooling Systems
  In IT infrastructure environments like data centers, server rooms, and other critical applications, the Ace Instruments immersion temperature series supports maintenance of ideal temperature. In IT infrastructure & data center cooling systems, deviation of temperature by a small degree creates a significant energy cost. The AI-200-T series supports facility managers in achieving the ideal environmental condition with high accuracy options including RTD Pt1000 (0.1 degree C accuracy), NTC 10k (0.1 degree C accuracy).
  
  
• Chilled & Hot Water Lines in Water Distribution Loops
  The AI-200-T series directly measures the liquid’s temperature with seamless data transmission to building HVAC and automation systems. The immersion temperature sensor uses high accuracy RTDs - Pt100, Pt1000 respectively as well as thermistors - NTC 10k. With the thermowell, the immersion temperature sensor is waterproof, allowing for easy installation and wiring. This makes temperature monitoring and control in chilled & hot water lines easy for users.
• Aggressive/Viscous Media Temperature Process Control
  The AI-200-T immersion temperature sensor is the ideal companion in all process applications where pressure, velocity or viscous, abrasive and corrosive materials are present individually or in combination. A temperature sensing element protected with an Ace Instruments thermowell will protect the temperature instrument from possible damage resulting from these process variables.
• Hygienic Food / Pharma Applications
  The AI-200-T series comes with an option of SS316 food grade stainless steel immersion sensor with thermowell. This makes it the ideal partner for food & beverage, life sciences, and pharmaceutical applications where the sensor comes into contact with aseptic processes.
  
  
• Building Automation Systems
  The resistance output of the immersion temperature sensors can be taken directly to
  
  • DDC controllers 
  • Energy metering systems 
  • VAVs 
  • Chiller/Boiler controllers
    
    This enables users to get real time datapoints and ensure process optimization for their application.
