|
RANGE
OF MOISTURE |
Sensor will measure up to
saturation of material. Usually around 15% in standard concreate
mixes, higher in lightweight aggregates. |
PENETRATION |
Approximately 75-100mm dependent
on material. |
SUPPLY
VOLTAGE |
Wide range power supply
input 15 - 30Vdc (recommended nominal supply voltage 24Vdc).
Requires approximately 140mA at +15Vdc, 100mA at 24Vdc. |
TEMPERATURE |
Operating temperature 0-60
degrees C. N.B. The sensor will not measure moisture in frozen
materials. |
ANALOGUE
OUTPUT |
Configurable 0-20mA or 4-20mA
current loop source. For 0-10Vdc output an external 500R load
resistor should be connected across the output at the control
system end. |
DISCREATE
INPUTS |
To synchronise data collection
and masking to an external trigger (ie paddle proximity indicator)
or to select between moisture and temperature analogue output. |
REFRESH
RATE |
Outputs are updated approximately
25 times per second. |
DIGITAL
(SERIAL) COMMUNICATIONS |
Opto-isolated RS 485 2 wire port. |
GROUNDING |
Sensor body is connected to cable shield. An
external earth lug is also provided. Ensure equipotential bonding
of all exposed metalwork. In areas with high risk of lightning
strike, correct and adequate protection is essential. |
