Setup of the SITRANS LR100 is easy

The Siemens SITRANS mobile IQ app is straightforward. See how quickly you can setup your SITRANS LR100 transmitter with your mobile device. 

Ignore obstacles in your application

The Auto False Echo Suppression feature allows you to ignore obstructions in your vessel. And, it’s easy-to-use! See how.

Digitalization and control

Take advantage of advanced functionality

SITRANS LT500 controller

The next evolution of level, flow, and pump controllers for radar or ultrasonic transmitters – or any 2-wire 4-20 mA device. It is the first choice for radar sensor measurements at 80 GHz and features single and dual point measurements, 6 relays, and Modbus RTU, HART, PROFIBUS DP, PROFIBUS PA, PROFINET.

SITRANS mobile IQ app

This app runs on your handheld device and provides ease of use to commission, diagnose, and maintain SITRANS Probe LU240, SITRANS LR100 and other process instrumentation.

SITRANS RD150 remote display

Install a display in a convenient location. SITRANS RD150 is a 2-wire 4-20 mA loop remote display with HART.

Benefits

  • Easy Bluetooth® wireless technology for easy and quick setup with Siemens SITRANS mobile IQ App 
  • 80 GHz narrow beam and small size allows for the easiest installation and commissioning
  • Custom radar microchip means signal killer conditions like condensation, buildup or fluffy solids are no match for the extreme sensitivity of the microchip, the weakest signals are still detected
  • Zero blanking zone allows measurement range right up to the sensor and with an accuracy of 2 mm you can get rid of costly manual measurement methods
  • Digitalization and Industry 4.0 ready with HART 7.0 or optional Modbus RTU for intelligent, value adding data locally or to the cloud

Supplementary Components are designed to work with most types of instrumentation to provide enhanced functionality such as remote displays and remote monitoring solutions. Please find more information here.
