Analog Tensiometers

Product catalog summary

Introduction
The document discusses the importance of Analog Tensiometers in agriculture, particularly in the context of increasing food demand and decreasing water resources. These devices are crucial for efficient water management and soil moisture monitoring.

Main Features
The Analog Tensiometer is similar to traditional tensiometers but uses an Electronic Vacuum sensor (Analog Transducer) instead of a mechanical gauge. This allows for:

Continuous, long-term soil moisture monitoring without physical presence on-site.
Access to real-time and historical data via various devices like PCs, smartphones, and tablets.
Optional automatic irrigation control based on soil moisture levels.

Specifications
The tensiometer's body is consistent with other Ami-Tens models, featuring a TEE connector for the Analog Transducer and a cap for water refilling. The transducer is a stainless steel cylinder available in two sizes (6cm or 10cm length, 2cm diameter) with a G1/4" threaded connection.

Electro-Mechanical Details
The transducer converts water tension into electrical outputs, available in two models:

4-20mA output for currency changes.
0-2V output for voltage changes.

These outputs reflect soil moisture changes proportionally.

Measurement Range

Standard model: 0-100 CB (Kpa) or 0-1000mB.
Low Tension model: 0-200Mb, suitable for soilless media or sand.

Operation Power

4-20mA model: 10-24V.
0-2V model: 3-12V (stabilized inlet).

Additional Information

Temperature compensation is effective between 0-70°C.
The cable length between the sensor and the logger can be up to 200 meters.

General Remarks

The water refill cap must be hermetically sealed.
To prevent algae growth, add a few drops of chlorine solution or cover the transparent part with aluminum foil or another material.
Specify the required measuring depth when ordering.

Analog Tensiometers An Analog Tensiometer, is principally identical to any other Tensiometer, with one major difference: Instead of having a mechanical gauge there is an Electronic Vacuum sensor, also named Analog Transducer, that transmits, via cable, vacuum readings to a computerized monitoring or control system. The Transducer converts Physical values (water tension) to electrical standard outputs. There are 2 basic models, differing from each other by the output mode: a) 4-20mA output, to measure Currency changes, The main use: • Continuous, long term follow-up of soil moisture changes with...
