In Situ Amplifier and Connector System
Robust sensor signals and ease-of-use
The Unisense In Situ Amplifiers are built to give signal amplification close to the sensor tip for stable and low noise signal path. The In Situ Connectors are allowing easy sensor replacement during field work.
The In Situ Amplifier and Connector System is an integrated part of our Field Systems portfolio including MiniProfiler MP4, UnderWater Meter and our DeepSea Lander solutions.
- Rated to 300m depth – optional to 6000m
- High quality and robust signal amplification
- Easy sensor replacement during field work
In Situ Amplifiers
Microsensors are sensitive and extremely accurate measuring tools. To avoid that the minute sensor signals (pA or mV) are influenced by background noise, the Unisense In Situ Amplifiers (ISA) are integrated in the cable connecting the sensor to the datalogger and convert the sensor signal to a robust voltage signal already at the microsensor base. The ISAs thus function as miniaturized pA- or mV-meters and ensure high quality signals.
The ISAs are sensor type specific and facilitate polarization of the sensor and amplification of the signal. All channels of your Field System can therefore be connected to any ISA. Amplifiers can easily be interchanged, both within and between instruments, giving you total flexibility for future studies.
In Situ Connectors
The Unisense In Situ Connector system is designed for mounting of sensor on the ISA and for easy replacement of sensors while in the field.
- Simple snap-on mounting
- Protection of sensor tip during handling and preparation
- Improved shielding for very stable signals both in the lab and in the field
- Providing pressure compensation at all depths
