Bio Instruments FI-x-PT Fruit Growth Sensors
Fruit Growth Sensors Quick Start Guide
www.phyto-sensor.com
Introduction
A PT-series of the FI-type absolute displacement sensors provides recording
both size and growth rate of intact rounded (like tomato and apple) and oblong
(like cucumber and banana) fruits in three diameter ranges within 7 to 160 mm.
Original parallelogram design of moving arms provides firm and straight
positioning of the sensor on a fruit under study. The PT-series sensor has a
built-in precision displacement transducer with a miniature DC-powered signal
conditioner.
Installation
- Choose a fruit for attaching the sensor.
- Move clamping jaws apart so as the sensor can hold the fruit in the desired position.
- Check if the sensor holds the fruit firmly and cannot easily slide down with application of gentle force.
- Secure the sensor’s cable on a stem to prevent occasional movement of the sensor.
- Check the position of the sensor regularly.
Connection
The connection table:
| Pin | Color | Description |
|---|---|---|
| 1 | Black | Ground |
| 2 | White | Output 0 to 2.4 Vdc |
| 3 | Red | Power 2.8 to 16 Vdc @ 1mA typ. |
Power supply
The PT-series sensors are to be powered from an external regulated power
supply with 2.8 to 16 Vdc @ 1mA typ. output voltage.
