MP100H/MP400H

The MP100H/400H is an advanced series of probes that offer high accuracy and fast response for meteorological applications. In the standard units, humidity is measured with the plug-in HygroClip digital probe and temperature is measured by a separate fast response RTD probe. The MP100H has two linear voltage output signals. A built-in cable length compensation permits error-free signal transmission over distances up to 100m/300ft. The MP400H has two linear current output signals and allows transmission over even greater distance. For application where a separate RTD probe is not required, the temperature output signal is provided by the HygroClip using the 1/3 DIN RTD located next to the humidity sensor.

All weather protected

The barrel of the MP100H/400H is designed to protect the internal electronics under all weather conditions. All connectors and cable entry points have special seals to prevent moisture entry. The electronics are conformal coated for protection against high humidity conditions. Once the electronics have been factory adjusted and calibrated, there is never a need to open the barrel. Calibration of the HygroClip is fully digital (no potentiometers) and the separate RTD is extremely stable.

Separate temperature probe

The separate temperature probe consists of a Pt100 RTD protected by a stainless steel tube. This probe provides fast response and can easily by calibrated in a cath after removing the HygroClip.

The standard porbe uses a 1/3 DIN RTD with a maximum deviation of ±0.1°C at 0°C from the DIN standard. As an option, 1/5 DIN (±0.06°C) and 1/10 DIN (±0.03°C) RTDs are also available. The MP100H/MP400H can be ordered with a direct RTD connection: 2, 3, or 4-wire

HygroClip-S3

The HygroClip-S3 digital humidity-temperature plug-in probe has two analog outputs signals and a one-wire digital output. The operating range is 0...100%RH and -40...60°C. Standard factory calibration results in an accuracy of ±1.5%RH and ±0.2°C at 23°C.

The HygroClip offers true, 100% interchangeability. Unlike products that only feature a plug-in or interchangeable sensor, the HygroClip can be replaced in seconds without any calibration and without any loss of accuracy. Inside the HygroClip, a non-volatile memory retains the calibration data, sensor characteristics, serial number, etc. ROTRONIC offers easy-to-use software and accessories for in-house calibration. If you do not wish to calibrate, or if the HygroClip needds replacement, use the unique HygroClip exchange program. This plan is supported by the ROTRONIC worldwide distribution network. The fully calibrated replacement HygroClip-R3 always contains a new humidity sensor and a bran new filter.

Radiation shields

RS41004-7A natural aspiration shield. Optimum protection against rainfall and sunshine. Suitable for horizontally incident rain up to 68km/h.

VHTS1 compact, motor aspirated radiation. Supply voltage 10...16 VDC or 24 VDC. Optimum protection in all weather conditions (mountain, sea, desert, etc.). Available with white or Ematal coating.

Electrical connections

Connecting cable
A PUR cable, white with 7 cores and shield is used for the standard probes. A 10-core cable is used for the optional direct RTD connection (additional temperature probe).

Cable compensation MP100H
The wire labelled SIG 0 should be connected together with the GND wire at the end of the connecting cable.

Digital output
The Digital output (DIO) transmits only the signals from the HygroClip. The DIO is well suited for further signal processing in a central unit. The maximum cable length for the DIO signal is 5 m (15ft).
