  • Overview
  • Series Specifications
The CRL Series remote mount carbon dioxide sensor is designed for use in HVAC control applications. Inside buildings, people are the major source of CO2. By controlling fresh air based on CO2 levels, energy can be saved and tenant comfort improved. The CRL Series ensures that adequate ventilation is provided, while maximizing energy savings by ventilating at the optimum level.

APPLICATIONS

  • Controlling HVAC in response to occupancy
  • Improving tenant comfort
  • Facilitating compliance with ASHRAE 62.1-2004 standard for air quality
  • Direct measuring of outside air or sample from other remote area
Microprocessor design reduces long-term drift and calibration requirements
  • Non-dispersive infrared technology (NDIR) repeatable to ±20 ppm 0-2000 ppm range
  • Innovative self-calibration algorithm
  • 5-year calibration interval (recommended)
  • Low ambient sensitivity
  • Field-selectable 4-20mA/0-5V/0-10V output
  • Comes complete with AA50 3 ft long duct pickup and filtered sample tube assembly
  • LCD display
  • Alarm relay output to trigger HVAC equipment at predetermined level
  • Input Power 20 to 30VDC/24VAC; 100mA maximum
  • Analog Output 4-20mA, (clipped & capped)/0-5VDC/0-10VDC (selectable)
  • Operating Temperature Range* 0° to 50°C (32° to 122°F)
  • Housing Material High impact ABS plastic
CO2 Transmitter:
  • Sensor Type Non-dispersive infrared (NDIR), diffusion sampling
  • Measurement Range 0-2000/5000 ppm (programmable)
  • Accuracy ±30 ppm ±5% of measured value
  • Repeatability ±20 ppm ±1% of measured value
  • Response Time** <60 seconds for 90% step change

* When directly measuring outside air, ensure the temperature of the air as it reaches the sensor is between 0° and 50°C.** Response time when used with 3ft long sampling tube, Veris part number AA50.EMC Conformance: EN 61000-6-3:2001 Class B, EN 61000-6-1:2001, EN 61000-3-2:2000, EN 61000-3-3:2001, EMC Test Methods: CISPR 22:1997 (Amended A1:2000, A2:2002) Class B, IEC 61000-4-2:2002, IEC 61000-4-3:2006, IEC 61000-4-4:2004, IEC 61000-4-5:2001, IEC 61000-4-6:2004, IEC 61000-4-8:2001, IEC 61000-4-11:2004.EMC Special Note: Connect this product to a DC distribution network or an AC/DC power adaptor with proper SURGE PROTECTION (EN 61000-6-1:2001 specification requirements).
