Description

PULSAR IMP Self Contained Ultrasonic Level Measurement

Pulsar’s IMP range is non-contacting ultrasonic level measurement without compromise. Compact, low-profile self contained units with the benefit of digital echo processing specially designed for IMP. Simple programming without affecting the IP rating via the integral keypad or using IMP PC, IMP’s own PC software that lets you program the unit, view and download echo profiles and parameters.

You can use IMP wherever you need reliable non contacting level measurement: digital echo processing means IMP is perfect for solids or liquids. Sumps, tanks, silos. Anywhere you need a display telling you the level, or an analogue output to interface with your site control system or drive a display.

When used on battery power for intermittent (wakeup)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.

FEATURES:

Compact self contained level measurement.
Calibrate without compromising the IP67 rating.
Simple menu led set up.
High power and narrow beam angles.
1.5” universal thread (2” on IMP 10).
Agitator avoidance as standard.
200mm deadband on IMP 3.
PVDF Nose option.

IMP APPLICATIONS:

You can use IMP wherever you need reliable non-contacting level measurement: digital echo processing means IMP is perfect for solids or liquids. Sumps, tanks, silos. Anywhere you need a display telling you the level, or an analogue output to interface with your site control system or drive a display.
When used on battery power for intermittent (wakeup) 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 40μA (3 seconds “live” @ 12mA averaged over 15 minutes).
The presence of active and passive (sourcing and sinking) analogue outputs assists with system integration, especially when retrofitting into older installations.

IMP PC:

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 units without even removing them from the application.

Flow measurement.

A flow curve may be added within IMP PC to configure for simple level to flow linearisation.

PC Interface IMP PC	All parameters can be accessed and changed through IMP PC software. Echo traces may be viewed on screen. NB: IMP I.S. does not offer this feature.

INSTALLATION:

The compact IMP is only 175mm high with a 130mm diameter.
Cable glands are provided and IMP can be simply screwed into a 1.5” or 2” universal fitting (a 1.5” to 2” adaptor is available).
High transducer power and tight beam angles, together with Pulsar’s digital echo processing, makes IMP ideal for many “difficult” applications such as dusty or foamy environments, or where a tank has unavoidable intrusions.
The integral display makes programming IMP is extremely straightforward.
IMP can be completely set up, without compromising the IP rating, using the integral keypad alone with no need for a PC.
Optional IMP PC software makes it easy to fine tune IMP’s performance and “clone” any number of IMP units to the same settings if, for example, they are being used on a tank farm.
Please note that PC interface is not included on I.S. IMP variants.
