Supported Applications
The Omega CMDP Series is a family of low-cost chilled mirror dew point transmitters configured as duct, wall, pipe, or OEM units. The series utilizes primary measurement principles to provide stable, accurate, and repeatable measurements traceable to NIST.
- Duct mounted applications (CMDP-D)
- Wall mounted applications (CMDP-W, CMDPT-W)
- Pipe mounted applications (CMDP-P)
Operating Conditions & Performance
The series operates within a process temperature range of -40°C to +60°C. Measurement capabilities include dew point from -20°C (@ 25°C) to 60°C (non-condensing), and down to -40°C when the sensor body is at 0°C. An optional air temperature probe supports measurements from -40°C to 120°C.
- Accuracy: ± 0.5°C for both dew point and temperature
- Repeatability: ± 0.05°C
- Resolution: 0.01 %
- Air Velocity: 50 to 900m/min
The unit requires a power supply of 24Vdc +/-3V @1.0A and has a pressure rating of 2 ATM (per data sheet) or 5 ATM (per manual). Wetted materials include Nickel, ultem, and anodized aluminum.
Configuration Options
The CMDP Series offers configurable mounting styles and measurement types. The series supports two 4-20mA outputs that are factory scaled for -20°C to 60°C unless specified on the purchase order. An RS232 communication connection is available via a 12-pin terminal block.
Mounting Configurations
- Duct mounted (CMDP-D)
- Wall mounted (CMDP-W, CMDPT-W)
- Pipe mounted (CMDP-P)
Sensor Options
An air temperature probe is available as an optional accessory for wall and OEM configurations. The probe connects via 4 Wire flying leads.
Key Product Differences
The series distinguishes models by mounting location and measurement capability:
- CMDP-D: Duct mounted chilled mirror hygrometer (dew point only)
- CMDP-W: Wall mounted chilled mirror hygrometer (dew point only)
- CMDPT-W: Wall mount chilled mirror hygrometer with dew point/air temperature
- CMDP-P: Pipe mounted chilled mirror hygrometer (dew point only)
Maintenance involves cleaning the mirror using a wetted cotton swab to restore normal operation. Settable service cycles are available for balancing and cleaning.
