Fruit Dendrometer (Type DF2)

For measuring changes in diameter of fruits and vegetables

User Manual

Version 2.0

Fruit Dendrometer –Type DF2

1. Introduction

Thank you for purchasing an Ecomatik Dendrometer type DF2. This is a highly precise sensor

for continuous measurements of diameter changes of fruits and vegetables under both indoor

and outdoor conditions.

This manual is written to help you install and operate your DF2 dendrometer with least difficul-

ty and for desirable results. Please read it carefully before installing the sensor, and refer to it if

you should have any difficulty with the sensor in the future.

The dendrometer is the sensor part of a measuring system. This means that the dendrometer

must be connected to a data logger for continuous data recording. The dendrometer is com-

patible with the most data logger types. At Ecomatik a low-cost, special for dendrometers de-

veloped DL18 logger is available.

2. Product Description

The picture below shows the contents of delivery. Please contact us should you miss anything

of these items.

Fruit Dendrometer

The standard cable length is 5 m. if you ordered cable extension, the cable length is the or-

dered extension + 5 m.

To meet the requirements of different loggers, there are 2 different types of cables: cable with

plug and cable without plug. Cable with plug can only be connected to Dendrometer Logger

DL18. Cable without plug can be connected to other loggers.

3. Safety Information

The sensor is protected from rain water, but it is not waterproof. Please do not immerse the

sensor in water, or install the sensor below a longer lasting snow cover.

Fruit Dendrometer –Type DF2

Avoid any tension between the cable and sensor during handling and operation.

Pay attention to connections to data logger. Wrong connections will provide wrong readings.

4. Installation

Tools: Cable strap, spanner (M3), screw driver, and rope.

Depending on the type of fruits, there are 3 kinds of installation: small fruits, big fruits and

elongated fruits. The photos below show how the fruits are fastened to the dendrometer.

Generally, it must be ensured:

Tighten all screws firmly and the frame is stable.

The dendrometer bears the weight of fruit.

The cable does not pull on the sensor.

No rain water flows into the sensor.

The sensor rod is slightly pushed in by 2-3 mm.

5. Wiring and Logger Configuration

The dendrometer is compatible with most data loggers. In the following we describe the con-

nection with Dendrometer Logger (DL18), Campbell Logger (CR1000). Please contact us if

your logger is not described here.

Dendrometer Data Logger (DL18)

The DL18 is a battery powered, waterproof logger for connecting 4 dendrometers. It is a very

effective data logger for dendrometer measurement under outdoor conditions. For details

please see the user manual of the DL18.

Campbell Data Logger (CR1000)

The dendrometer can be measured both in single-ended voltage as well as differential voltage

mode. Differential voltage mode provides better accuracy. But single-ended mode requires half

as many channels as differential mode. One CR1000 can include 16 dendrometers in single-

ended mode, but only 8 dendrometers in differential mode.

An interval 0.5-hour for data collection can reveal the diurnal course of diameter changes very

well.

5. Adjustment and maintenance

Fruits usually grow very fast, the diameter can grow to 0.5 mm per day. It is therefore very im-

portant to pay attention to the reset of the sensor. When the output approaches 25 mm, the

sensor needs to be reset. Relax the screws and let the sensor again at the position where the

sensor is pushed in about 2-3 mm.

Accuracy:

Dendrometer dependent:

Max. ±1.97% of reading (stable offset)

Dependent on the connected data logger, e.g.:

CR1000:±(0.04% of reading+10µm)

Dendrometer logger DL18: ±0.1%

Temperature coefficient

of the sensor:

<0.2 µm / °C in the whole range

Linearity:

<0.7%
