PTU50 Ultrasonic level transmitter Range 0.05 *lm Blind zone 5 cm IP67|68 Suitable for measuring of liquids MODBUS RTU/BLUETOOTH comm, protocol Power supply 24 Vdc Output: 4*20 mA analogue output Non-intrusive level measurement systems are the preferred technology for many applications and for this reason SGM-LEKTRA developed the level/distance transmitters PTU50. These units are compact with a unique simplicity of commissioning. Calibration and transmitter configuration is possible, even remotely, thanks to a MODBUS RTU connection together with the related software for the PC, or via VLW90M / VLW60T display unit.The IP68 transmitter protection allows installation in underground wells. Accuracy ±0,2% (ofthe measured distance) not betterthan ±3mm Resolution 1mm Calibration VLW90M/VLW60T prog. module or by MODBUS Warm-up 30 minutes Display LCD display on VLW90M;VLW60T; VLW602 (opt.) Technical Features Housing material PP Mechanical installation 1”GAS M-PPfl ange DN100 opt. Protection degree IP67|68 Electrical connection IP67 male connector with 5/10/15/20m linking cable Working temperature -20 ± +60°C Pressure From 0,5 to 1,5 bar (absolute) Power supply 20±30Vdc Power consumption 1.5W Analog output 4±20mA max 750ohm Digital communication MODBUS RTU Range 0.05-lm In case of non perfectly reft ecting surfaces, the maximum distance value will be reduced Temperature compensation digital in the working temperature

Ultrasonic for measurement in liquids and muds Range: 0,05 * 1m; IP67 / IP68 proof Housing in polypropylene (PP) Calibration by VLW60T / VLW90M units or via MODBUS Power supply 20*30Vdc - Output 4*20mA + MODBUS Temperature range -20 * +60°C
