SENSOR DESIGN

Casing: High Grade Steel V2A 1.4301

Exchangeable especially wear-resistant sensor head: hardened special steel with highly wear resistant ceramic window.

Available upon request: Version for applications with most extreme abrasion.

MEASUREMENT RANGE MOISTURE

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

MEASUREMENT RANGE TEMPERATURE

Measurement Range: 0°C …100°C

The temperature is measured at the sensor casing beneath the wear-resistant sensor head and can optionally be issued at the analogue output 2. The material temperature can be measured with an external calibration and compensation of the sensor intrinsic-heating.

POWER SUPPLY

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

SIGNAL OUTPUT

2 x Analogue Outputs 0(4)…20mA

Output 1: Moisture in % (variably adjustable)

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

In addition, there is the option to split the analogue output 2 into two ranges, into 4..11mA for the temperature and 12..20mA for the conductivity. The analogue output 2 hereby changes over in 5 second cycles between these two (current) measurement windows.

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

COMMUNICATION

A RS485 interface enables network operation of the sensor, whereby a data bus protocol for the connection of several SONO sensors to the RS485 is implemented by default. The connection of the sensor to industrial buses such as Profibus, Ethernet, etc. is possible via optional external modules (available upon request).

MEASUREMENT FIELD EXPANSION

Approximately 50 - 80 mm, depending on material and moisture.

MOUNTING

Sensor Dimensions: 108 x 132mm (Diameter x Length)

The mounting and fastening frame can be mounted to the rear side of the mixer base or the outer wall of the mixer. For this purpose, it is adjusted with the help of the additional welded on mounting frame. This enables the easy mounting and dismounting as well as the adjustment of the sensor position in case of wear at the mixer base.

MEASUREMENT RANGE CONDUCTIVITY

The sensor, as a material-specific characteristic value, delivers in respect to the cement content or the slope of fresh concrete, the radar-based conductance (RbC – Radar-based-Conductance) in a range of 0…50dS/m. The conductivity range is reduced in measurement ranges >50%.

MEASUREMENT DATA-PREPROCESSING

MEASUREMENT MODE CA: (Cyclic-Average) For relative short measuring processes with continual average value, filtering and an accuarcy of up to 0.1%.

MEASUREMENT MODE CF: (Cyclic-Float-Average) For very slow measuring processes with floating average value, filtering and an accuarcy of up to 0.1%.

MEASUREMENT MODE CS: (Cyclic-Successive) For very short measuring processes without floating average with internal up to 100 measurements per second and a cycle time of 200 milliseconds at the analogue output.

AMBIENT CONDITIONS

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

CALIBRATION

The sensor is provided with a universal calibration. A maximum of 15 different calibrations can be stored. For special materials, variable calibrations with polynomials up to the 5th order are possible and can be downloaded into the sensor with the SONO-CONFIG software. A zero point correction can be performed easily with the SONO-CONFIG software.

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.
