The Ultrasonic Level Transmitter Type ECH_0101X_DC combines an ultrasonic sensor and a transducer with a large 2x20-digit LCD display in IP68 cast aluminium enclosure. The transmitter is powered with 15-30 VDC and has a 4-20 mA output and RS485 Modbus serial port for a PLC, or for monitoring. Four 1A relays can be configured as latched for automatic fill or empty operations. The transmitter includes a range of fail-safe features. Signal loss, power supply failure, level alarm can be activated with an adjustable time delay.
A range of filter functions control the return echoes and automatically eliminate all interference.Easy and fast commissioning is guaranteed with Simulation functions. Different tank shapes (cylindrical, cubic, spherical) can be easily programmed via fixed default shapes.
The simulation functions allow the system to be tested under dry-run conditions.The measured value can be shown as level, distance (in cm, m, inch or feet), or direct as volume (liter, m 3 , imp. gal, U.S. gal).
Applications include:
- Non-contact continuous level or volume measurement with all liquids in open or closed vessels
- Distance and movement supervision
- Waste engineering, water treatment and process technology
- Food industry
- Chemical and pharmaceutical industry Specifications Power: 15-35 V DC 4W Max Control relay: 250VAC 1A 4 Sets Fail safe relay: 250VAC 1A 1 sets Analog output: 4-20mA opticaly isolated (2kv) 14bit Communication: RS485 opticaly isolated (2kv) Modbus Up to 38400 bps Working temp.: -10°C to +60°C Prob Protection class: IP68 Resolution: 1mm Max Linearity: Better than %0,7 Distance: 11m Max for liquid Sensor Frq : 50Khz Beam Angle: 10 Deg Compensation: Temperature compensated
