4 Report No. M Page 4 of Description supplied by Client The EUT is the SULTAN Series Acoustic Wave Level Transmitter. It measures distance to the level of liquid or solid material in a vessel. The measured material level is communicated to control equipment, such as a PLC, via a 4-20mA current loop. The level is normally monitored by sensing the voltage across a precision resistor in the current loop. The SULTAN series equipment may be powered by an V universal AC input or by 24V DC. The equipment is available in a range of acoustic operating frequencies and is available as both an integral transmitter configuration (amplifier + transducer) and as a remote configuration where the amplifier is connected to the transducer via a screened multi-core cable. 2.2 Operating Conditions The EUT was powered up, measuring the distance to the nearest chamber wall. The output current was measured during the different tests. The status of the distance dependent relay outputs was also noted.
