Eddy Correlation Amplifier Housing
Amplifier Housing - Impulse

Picture right is the amplifer housing and sensor holder.
Amplifer uses Impulse 5-pin oil filled connectors. Connectors
are pressure rated to ~340 atmosheres.

Female (connects with electrode) minature high density 5-pin
oil filled : MHDG-5-CCP-OF
Male (connects with amplifier) minature high density 5-pin oil
filled : MHDG-5-BCR-OF

Pin specifications above are from Peter Berg, color labeling
is same as for Anni Glud's sensors. Although a 3-pin
connector could be used, we stay with 5-pin in the event
another constituent would be measured (e.g. temperature)

Amplfier Housing - Impulse vs. Kemlon Connection




Above is current SAMS
system. They will move
towards the Kemlon
connector (right side).

Above is the same basic design as the impulse version, only the front
needs to be relaced for Kemlon connector. Click for sketch.

Advantages of Kemlon Connection:
- Higher Impedance (less signal loss)
- Others?

Advantages of Impulse Connection:
- About 5x less expensive than Kemlon
- Easier to polarize and quickly mount to amplifier
- extra (5-pin) pins allow logging of additional parameter
- Others?
