Vaisala DMT242 Dewpoint Transmitter
The Vaisala DRYCAP® Dewpoint Transmitter DMT242 provides reliable and stable measurements for low dewpoint industrial dryer applications. It provides fast response time and wide measurement range: measuring from -60 to +60 C (-76…+140 F) with an accuracy +/-2 C (±3.6 F) over the entire specified process temperature range.
Features:
- Ideal choice for low dewpoint industrial dryer applications.
- Incorporates advanced Vaisala DRYCAP® Sensor and enhanced auto-calibration software.
- Long-term stability in low dewpoints.
- Fast response time.
- Wide dewpoint measurement range from -60…+60 C (-76…+140 F) with an accuracy +/-2 C (±3.6 F).
- Withstands condensation.
- IP65(NEMA 4) housing provides protection against dust, dirt and splashed water.
- Can be installed directly into systems at 20 bar maximum pressure.
- NIST traceable (certificate included).
- Compatible with Vaisala DRYCAP® Hand-Held Dewpoint Meter DM70.
Vaisala DRYCAP® performance
DMT242 incorporates the Vaisala DRYCAP® thin film polymer sensor and auto-calibration software, a combination that makes it ideal for use in dry ambients. The sensor is immune to particulate contamination, water condensation, oil vapor and most chemicals. Because the sensor withstands condensation, its performance is unmatched for low dewpoint applications that experience process water spikes, such as pipeline condensation during a system failure or start-up.
The auto-calibration software works on-line while the process is running. If the measurement accuracy is not confirmed, the software makes the corrections to the calibration curve. Corrections may be due to contamination, or aging of the sensor. In either case the transmitter adjusts the measurement, corrects dry-end drifts and continues to function. Calibration occurs quickly, and with corrections so minor, the user will not realize it has taken place.
Compact, rugged and intelligent
The DMT242 is designed for extreme conditions that require protection against dust, dirt and splashed water. The housing offers IP65- protection and the transmitter can be installed directly into systems at 20 bar maximum pressure. Due to its compact size, DMT242 is quickly and easily installed in tight spaces. Units are delivered installationready. If necessary, re-scaling the output can be done via the serial interface. The supply voltage and output signal connect easily to the IP65 (NEMA 4) protected screw terminals. A separate serial output is available for service use.
