Functional Description TRIME-PICO IPH
The intelligent and compact TRIME-PICO IPH sensor is a measurement device for portable and
non-destructive determination of volumetric soil moisture in a profile. This system is designed
for portable field use. A variety of installation options (tubes are available in 1m, 2m and 3m)
offer a wide range of applications.
TRIME-PICO IPH can be used in different system configurations with either our display unit
TRIME-HD to display the soil moisture value in the field. Alternatively it can be used together
with a PDA (with the software PICO-Talk) in combination with the PICO-BT Bluetooth module.
This system offers the ability to store the measurements and to handle different sites, sensors
and depth. Also you are rid of annoying cables.
Your sensor is supplied ready for use and works in a wide range of standard soils. For further
information please check the details under Section 6!
1.1
Operation modes
The TRIME-PICO IPH is supplied with an RS485 interface and analogue output of 0..1V for soil
moisture.
The TRIME-PICO IPH can be easily connected to:
-
PICO-BT Bluetooth module
-
TRIME-HD analog display unit
-
GlobeLog (special application in Version IMP-Bus)
-
Analog-Loggers (special application)
A detailed description of how to select a specific operation mode for your application can be
found below.
PLEASE NOTE: Analogue dataloggers require differential inputs!
1.1.1
Operation mode A (Protocol communication)
In the standard version the TRIME-PICO IPH will be delivered with RS485-Interface, as it’s re-
quired for the use with the PICO-BT Bluetooth module. If the TRIME-PICO IPH should be con-
nected to the GlobeLog a special version with IMP-Bus has to be ordered.
If multiple sensors are to be wired as a network, IMKO offers 3-port, 6-port and 12-port distri-
bution modules (only for IMP-Bus). Please note that the RS485/IMP-Bus cable length and cable
diameter must be properly matched as otherwise the energy consumption of the TRIME sensors
(100mA @ 12V/DC for 2..3s) may cause a drop in voltage.
More information is available in Sec-
tion 5.
For use with:
PICO-BT Bluetooth module
IMKO calibration and test software TRIME-Tool (see www.imko.de) with convert-
er module SM-USB or PICO-BT module
GlobeLogger (Special version with IMP-Bus)
EnvisLog (PC-Software for Microsoft Windows) only with converter module SM-
USB
1.1.2
Operation mode B (Single measurement)
The TRIME-PICO IPH will perform a single measurement when the power is switched on. Once
the measurement has been taken (2..3s) the readings are supplied as analogue output signals
