Description 3
3.1 Applications
The SITRANS DA400 acoustic diagnostics unit acoustically measures the structure-borne
sound of oscillating displacement pumps.
The SITRANS DA400 allows continuous, simultaneous and independent monitoring of up to
four delivery valves in a pump for leaks. In addition, another four inputs are available for
monitoring standard signals (e.g. diaphragm and temperature monitoring). This means that
the condition of an oscillating displacement pump is monitored in every phase of its
operation.
The SITRANS DA400 is used in all industries where oscillating displacement pumps are
used.
3.2 Operation
You can operate and configure the SITRANS DA400 using the keys. In parallel, you can also
operate the SITRANS DA400 via a PROFIBUS connection.

3.4 How It works
SITRANS DA400 with protection against explosion
3-4 Operating Instructions, 02/2006, A5E00684661-01
3.4 How It works
3.4.1 Measuring principle
Leaks in the delivery valves of oscillating displacement pumps are flows in which cavitation
occurs. This results in sound waves that are transmitted to the valve housing, where they are
recorded by the structure-borne sound sensor in the SITRANS DA400 on the outside.
The SITRANS DA400 utilizes the fact that with both an open valve and a closed intact valve,
no cavitation occurs and the measured sound level thus corresponds to the operating noise
of the pump. By contrast, with a closed defective valve cavitation does occur, which can be
identified by a period increase in the sound level (see figures). The measured value from the
SITRANS DA400 corresponds exactly to this increase in the sound level.
The measurement is carried out exclusively in the ultrasonic range. This filters out the
operating noise of the pump and the closing noise of the valves.
Figure 3-2 Signal from structure-borne sound sensor with intact valve
Figure 3-3 Signal from structure-borne sound sensor with defective valve
3.4.2 Sensor operation
The structure-borne sound sensor works on the piezoelectric principle. The structure-borne
sound is injected into the sensor via the sensor base (mounting surface) and inside it is
converted into an electrical voltage by a piezoceramic element. This is amplified in the
sensor and transmitted via the cable.
The sensor frequency range lies in the ultrasonic range (>20 kHz). The sensor is non-
directional, i.e. the angle at which the sound wave is incident on the sensor base is not
important.

By using a bridge rectifier, the current from a suitable external feed splitter creates the
internal current voltage of 3.3 V and 8.2 V for circuit 2. The supplementary voltage UH is
obtained from the PROFIBUS-PA signal of an external coupler. Circuits 1 and 2 have split

potential regarding the current and each other. Circuit 1 consists of a microcontroller (µC2)
that is responsible for PROFIBUS communications. It is connected to the micro-controller
(µC1) in circuit 2 via a serial, split potential coupler. At the heart of this circuit is a signal
processor with integrated analog-digital converter for high-speed recording and evaluation of
the available signals. Moreover, an EEPROM safe from a voltage drop is activated for
storing data and the display, and the key strokes are read in.
The six digital outputs are separated individually by potential and designed for connection to
a NAMUR connection hardener. The maximum four acoustic sensors are connected to the
four-pole "Sens1" to "Sens4" blocks. In each case, two terminals provide the supply for the
sensor electronics and two terminals are used to connect the sensor signal.
Different standard signals can be connected at each of the four universal inputs "In 1" to
"In 4". The switching of the four terminals is to be set up according to signal or sensor type
(0/4 to 20 mA, digital signal for 24 V, closing contact).

4.1 Safety information for installation
Ambient temperature
Warning
Ambient temperature
When installing the sensor, attention should be paid to the surface temperature at the
installation location. For example, if you are installing the sensor on a pump, there is a risk of
burns if the pump is too hot.
4.2 Mounting
Overview
The device and the sensor are mounted in different ways. In general:
Note
Protection against harmful outside influences
To protect the device against harmful outside influences, a casing should be fitted. Harmful
external influences can occur if you install the SITRANS DA in the open air, where it can be
influenced by intensive frost, heat or rain.
Mounting the device
To mount the device, you need three screws with a diameter of 6 mm. These are not
supplied with the device.

Assembly
4.2 Mounting
SITRANS DA400 with protection against explosion
4-2 Operating Instructions, 02/2006, A5E00684661-01
The position of the mounting holes and the mounting dimensions in millimeters are indicated
on the rear of the housing.
The device should preferably be mounted vertically with the cable gland pointing downwards.
Mounting the sensor
Each acoustic sensor should be individually mounted on the outside of the pump or valve
housing, close to the valve to be monitored, using the enclosed M6 hexagon socket screw
and positioning pin.
There is a good acoustic coupling if no elastic elements such as seals or similar are located
between the sensor and the valve, i.e. there are good metallic connections.
As the structure-borne sound is injected into the sensors via their base, the substrate on the
housing must be uniformly even and smooth, and at least as large as the sensor base. To
improve the coupling, in certain circumstances a viscous lubricant can be used (not
included).
Note
Mounting the sensor
On pumps that have good acoustic coupling between the delivery and intake side, it can be
sufficient to use just one sensor for a pump head (with two valves). However, in this case it is
not possible to distinguish which valve has a leak.
The acoustic sensors are mounted at an equal spacing to the valves.
