Thiết đo độ ẩm vật liệu xây dựng IMKO SONO-SILO

Mounting

Sensor Dimensions: 55 x 350mm (Diameter x Length))

The sensor can be installed into silos with tube extensions. The length of the tubeextension is dependent on the installation facility. The mounting flange can bescrewed on to the rear side of any silo, container or hopper.

A pivot-retainer for the installation into a silo is available on request!

A gas- and waterproofed tube fitting is available on request!

Measurement range moisture

The sensor measures from 0% up to the point of material saturation. Measurementranges up to 90% moisture are possible with a material specific calibration.

Measurement range conductivity

The sensor, as a material-specific characteristic value, delivers the radar-based conductance (RbC – Radar-based-Conductance).

SONO-SILO Standard and PTFE: 0..12dS/m conductivity

SONO-SILO Concrete: 0...40dS/m conductivity

The conductivity range is reduced in measurement ranges >50%.

Measurement data-preprocessing

MEASUREMENT MODE CF: For slow measurement operations with the optionof the smooth mean value accumulation including filtering with accuracies of upto 0.1%.

MEASOREMENT MODE CS: For fast measurement operations (withoutaveraging) with up to 100 internal measurements per second and with a cycletime of 200 milliseconds at the analogue output.

Power supply

+7V to +30V DC, 1,5 W max.

Ambient conditions

0 - 70°C; A higher temperature range is available upon request!

Signal output

2 x Analogue Outputs 0(4)…20mA

Output 1: Moisture in % (variably adjustable)

Output 2: Conductivity (RbC) or optionally the temperature.

The two analogue outputs can be variably aligned with the SONO-CONFIGsoftware. For a 0-10V DC voltage output, a 500R resistor can be installed.

Calibration

The sensor is provided with a universal calibration. A maximum of 15 differentcalibrations can be stored. For special materials, variable calibrations withpolynomials up to the 5th order are possible and can be downloaded into thesensor with the SONO-CONFIG software (Download per Internet). A zero pointcorrection can be performed easily with the SONO-CONFIG software..

Communication

A RS485 interface enables network operation of the sensor, whereby a databus protocol for the connection of several SONO sensors to the RS485 isimplemented by default. The connection of the sensor to industrial buses suchas Profibus, Ethernet, etc. is possible via optional external modules (availableupon request).

Connector plug

The sensor is equipped with a robust 10-pole MIL flange connector. Ready made connection cables with MIL connectors are available in the lengths 4m, 10m, or 25 m.

Measurement field expansion

Approximately 50 - 80 mm, depending on material and moisture
