Pulsar - Model IMP+ -Ultrasonic Level Measurement without Compromise

When used on battery power for intermittent (wake-up) applications, IMP`s high speed boot up of circa 3 seconds maximises battery life. For example, if an IMP+ were switched on every 15 minutes for a 3 second reading, average current is a mere 40µA.

Active and passive (sourcing and sinking) analogue outputs assist with system integration, especially when retro-fitting into older installations.

IMP PC is optional software that extends IMP`s capabilities, allowing you to:

• Download, analyse and store echo profiles. A great way to see exactly what is happening in the application. Fine tuning for ultimate performance.
• Set-up IMP. All programming parameters are instantly visible in the IMP PC programming screens. Program the IMP unit on a desktop before installation, or clone a number of IMPs to save valuable time.
• Updates. Future-proof your IMP! Pulsar`s policy of continuous improvement means that we never stop developing our products. IMP PC allows new firmware to be installed into your IMP PC units without even removing them from the application.
• Flow Measurement. A flow curve may be added within IMP PC to configure for level to flow linearisation.

• High speed boot up requirements
• Narrow beam angle
