The Vaisala HUMICAP

®

Dewpoint

Transmitter DMT132 is an affordable

dew point measurement instrument

designed to verify the functionality of

refrigerant dryers. It is especially well

suited for OEM dryer manufacturers.

Direct Measurement

Cuts Costs

Direct outlet air dew point

measurement provides accurate

information about dryer functionality

and is more reliable than the

traditional method of measuring

refrigerator temperature only.

Knowledge of the real dew point

ensures high quality compressed air

at all times and enables customers to

optimize dryer capacity. This helps

to prevent investment in redundant

dryer capacity and avoid unnecessary

maintenance and costly malfunctions.

High Accuracy and

Long-Term Stability

The DMT132 provides optimal

performance in the operating range of

refrigerant dryers. In the measurement

range of -3 … 20 °C (+26.6 … +68 °F),

where the refrigerator dryers typically

operate, the Td accuracy is ±1°C (±1.8°F).

The instrument incorporates the

proven Vaisala HUMICAP

®

sensor,

which is resistant to compressor oil

and most other chemicals, thereby

providing excellent long-term stability.

Quick Installation and

Easy Field Checking

It takes just a few minutes to install

the DMT132 directly into a dryer or

compressed air line through a G1/2"

ISO thread. Vaisala sampling cells

can also be used. The loop-powered

electronics mean that wiring is easy

and power requirements are low. The

DMT132 operating voltages can be as

low as 10 VDC.

Verifying the performance of the

DMT132 is easy with the compatible

Vaisala hand-held DM70 or HM70

meters. The user can perform

possible adjustments with the Vaisala

HMK15 Humidity Calibrator.

The optional LED warning light tells the user when the defined dew point limit has

been exceeded.

Demand for dew point sensors to verify

refrigerant dryers is increasing. Direct

dew point measurement enables energy

savings and improved efficiency.
