Humidity Temperature Meteorological Probe
Model MP101A

The MP101A is a combined humidity and temperature probe designed primarily for outdoor applications. Operation from a DC voltage and low power consumption make the MP101A particularly suitable for operation at remote locations.

Energizing of the probe is required for only 0.25 seconds during each measurement. The linear output signals are consistent with the requirements of most data acquisition systems. Use of the newly formulated HYGROMER C94 humidity sensor results is exceptional resistance of contaminants. Advanced filter technology provides further protection. The MP101A can be used over long periods of time without any maintenance or recalibration.

DIRECT MOISTURE CONTROL
  • High accuracy over the full range of humidity and temperature.
  • Temperature operating range: -40..+60°C (-40..+140°F)
  • 0..100% RH humidity measuring range
  • Durable, stable sensors with low maintenance requirements
  • Advanced humidity sensor with exceptional resistance to contaminants

TWO BASIC CONFIGURATIONS
  • MP101A-C4/5 with 2 meters hard wired cable terminated by a connector (4 or 5-pin)
  • MP101A-T7 with a 7-pin connector directly on the probe.

The probe MP101A-C4 is supplied with a 4-pin CANNON connector and is fully interchangeable with the previous probes of the MP100 series. When the application requires a total length of cable in excess of 6.5ft (2 meters), either the probe MP101A-C5 or the probe MP101A-T7 should be used. Both probes feature a compensation that eliminates potential errors resulting from cable resistance for lengths up to 330ft (100 meters).
