Ultrasonic level transmitter

Burkert’s Ultrasonic Level Transmitter Type 8175 provides continuous level measurement at distances up to 10 metres. Integrating an ultrasonic sensor and a transducer with a large 8-digit multi-language display in a splash-proof IP65 or immersion-proof IP67 housing, the Type 8175 offers users a teach-In function for easy commissioning, and also delivers low total cost of ownership. Designed for use in water treatment, pharmaceutical, food and other hygiene-based industries, the transmitter is a non-contact filling level transmitter that can be used in both open and closed vessels. Simple to use, with its menu-guided operation and 8- digit alphanumeric display, the Type 8175 delivers fast and easy commissioning with its integrated “Teach-In” and “Simulation” functions. These allow different tank shapes (cylindrical, cubic, spherical) to be easily programmed via fixed default shapes, or at complex tank shapes step- by- step. Importantly, the simulation functions allow the system to be tested under dry-run conditions, and the resulting measured value can be shown as a level, a distance (in cm, m, inch or feet), or direct, as a volume (litre, m3, Imp. gal or US gal). Underpinning its reliability in continuous process environments, the Ultrasonic Level Transmitter integrates a range of fail-safe features, including signal loss, power supply failure, and level or temperature alarms, which can be activated with an adjustable time delay. In addition, a range of filter functions control the return echoes and automatically eliminate all interference due to elements of the vessel. The 8175 transmitter is powered with 18-32 VDC (optionally 115/230 VAC) and features a three-wire 4-20 mA output for direct control of a continuous control valve, interface to a PLC, or for monitoring. Two optional 3A relays can be also configured as alarms or latched for automatic fill or empty operations. Burkert offers the 8175 Ultrasonic Level Transmitter together with process control valves as a complete, easy to control system. The transmitter can be used with Type 6213 solenoid valves, Type 2030 diaphragm valves, Type 2712 continuous TopControl System, 8644 valve islands and third party vendor PLCs in one totally integrated, easy to commission system.
