Time of flight method, The sensor transmits ultrasonic pulses in the direction of the product surface There they are reflected. back and received by the sensor The transmitter Prosonic S measures the time t between pulse. transmission and reception From t and the velocity of sound c it calculates the distance D from the. reference point see the figure 4 to the product surface. From D results the desired measuring value,Flow Q across measuring weirs or open channels. Time of flight correction In order to compensate for temperature dependent time of flight changes a temperature sensor. NTC is integrated in the ultrasonic sensors, Blocking distance The level L may not extend into the blocking distance BD Level echoes within the blocking distance.
can not be evaluated due to the transient characteristics of the sensor and thus a reliable measurement. is not possible The blocking distance BD is dependent on the type of sensor.

Power supply supplied by the transmitter FMU90, Sensor heater for FDU91 The FDU90 and FDU91 sensors are optionally available in a version with sensor heater. The sensor heater needs an external power supply, The power for the heater can be supplied by the power supply RNB130 from Endress Hauser. The power supply for the sensor heater is connected to the brown BN and blue BU strand of the. sensor cable,Technical data,24 VDC 10 residual ripple 100 mV.
250 mA per sensor, If the sensor heater is applied the integrated temperature sensor can not be used Instead. an external temperature sensor Pt100 or FMT131 from Endress Hauser must be used. The transmitter FMU90 is available in a version with an input for the external temperature. sensor For details refer to Technical Information TI00397F. 6 Endress Hauser,Prosonic S FDU90 91 91F 92 93 95,Electrical connection.

Endress Hauser 7,Prosonic S FDU90 91 91F 92 93 95, Connection hints In order to avoid interference do not route the sensor cables parallel to high voltage or.
electric power lines and not close to frequency converters. Limitation of electrical safety, The protective conductor GNYE of the sensors FDU91F 93 95 must be connected to the local. potential equalization after a maximum distance of 30 m 98 ft. The protective conductor GNYE of the sensors can be connected at this locations. Terminal box,Transmitter FMU90, The cable shield serves as a return cable and must be connected to the transmitter without. any electrical break With the preassembled cables the shield ends in a black strand BK. With the extension cable the shield must be twisted together and connected to the BK. terminal The cable shield must not be connected to the local potential equalization. For easier mounting it is advisable to use the sensors FDU90 91 92 with a maximum cable length of. 30 m 98 ft as well For longer distances an extension cable with a terminal box should be used. Extension cables for the For distances up to 30 m 98 ft the sensor can be directly connected by the sensor cable For longer. sensors distances it is recommended to use an extension cable The extension cable is connected via a terminal. box The total length sensor cable extension cable may be up to 300 m 984 ft. Explosion hazard, In explosion hazardous areas sparks can cause explosions This may lead to serious or fatal injury. Additionally the device and installation may be seriously damaged. If the terminal box is installed in explosion hazardous areas all applicable national guidelines must. be observed, Pay attention to the measures and notes in Chapter Certificates and Approvals 21. Suitable extension cables can be obtained from Endress Hauser 23 Accessories. Alternatively cables with the following properties can be used. Number of cores according to the connection diagram 7 Connection diagram. Braided wire shield for the yellow YE and red RD core no foil shield. Length up to 300 m 984 ft sensor cable extension cable. Cross section 0 75 mm2 to 2 5 mm2 18 to 14 AWG,Up to 8 per core.
Max 60 nF between core and shield, For FDU91F 93 95 The protective conductor GNYE must not be within the shield. 8 Endress Hauser,Prosonic S FDU90 91 91F 92 93 95, Shortening the sensor cable If required the sensor cable can be shortened Please note. Do not damage the cores when removing the insulation. The cable is shielded by a metallic braiding This shielding serves as a return cable and corresponds. to the black BK strand of the unshortened cable After shortening the cable loosen the metallic. braiding twist it together securely and connect it to the BK terminal. The protective conductor GNYE which is present in some of the sensor cables may not be. electrically connected to the cable shield,FDU90 91 92 FDU91F 93 95. L00 FMU90xxx 04 00 00 xx 015, Colours of the strands YE yellow BK black RD red BU blue BN brown GNYE green yellow. The blue BU and brown BN strands is only present for sensors with heater. Endress Hauser 9,Prosonic S FDU90 91 91F 92 93 95,Installation.
Hazard of accidents, If sensors are not fastened properly they can fall down and cause serious injury and property damage. Only install sensors in areas that are stable and sufficiently able to take the load. Fasten sensors only with fastening material that is proper and suited for the environment. Risk of sensor damage,Do not use the sensor cable for suspension. Protect sensor membrane from damage during installation. Installation options,Examples A B C,L00 FDU9xxxx 17 00 00 xx 001.

Installation conditions for,level measurements,L00 FDU9xxxx 17 00 00 xx 003. If possible install the sensor so that its lower edge projects into the vessel. Make sure that the maximum level does not reach into the blocking distance BD see table. Do not install the sensor in the middle of the tank 2 We recommend leaving a distance 1. between the sensor and the tank wall measuring 1 6 of the tank diameter. Avoid measurements through the filling curtain 3, Make sure that equipment 4 such as limit switches temperature sensors baffles etc are not.
