Process Instruments (UK) Ltd. (Pi) is a global supplier, providing water analyser instrument solutions since 1998. With offices, a laboratory and new manufacturing facilities in Burnley (UK), with subsidiaries in Ireland and France and a company representative in China, Pi has a growing reputation for innovation with customers in over 50 countries, across 6 continents. A major part of Pi’s business is through Private Label/OEM agreements, so the name ‘Process Instruments’ is not as widely known as many of our competitors. Instead of focusing on building a brand name we instead aim to provide our customers with the most reliable, flexible, and arguably the best water quality analysers on the market.
Highest Quality – Low Cost – Superior Functionality
Part of a range of controllers, the CRIUS®4.0 is the big brother of the CRONOS® and offers more sensor connections, more functionality and more flexibility with a colour screen and optional built in 3G/4G modem or LAN adaptor. The CRIUS®4.0 is an attractively priced, top of the range instrument controller. Optional communications options and optional Remote Access utilising the Internet of Things (IoT) MQTT protocol, the CRIUS®4.0 is fully Industry 4.0 compliant with live, encrypted data available across multiple platforms.
The CRIUS®4.0 is equipped with the capability to connect up to four sensors of any type with appropriate analogue outputs and relays. Four sensors not enough? Simply connect up to 4 CRIUS®4.0 together all using the same display and communications. Equipped with data logging as standard and multiple PID loops as options, the CRIUS®4.0 is very able to control complex water treatment processes at a fraction of the cost of other controllers. With all users having their own log on, and with three levels of instrument and remote access security, you can use the CRIUS®4.0 with all of its superior functionality with confidence.
KEY Benefit :
The CRIUS®4.0 controller provides users with numerous benefits:
- Multi-Sensor – reduces costs
- Onboard PID and other controls – reduces cost and improves process control
- Onboard data logging
- Remote Access via MQTT – live results anywhere in the world
- Industry leading autocleaning options for sensors – reduced maintenance and cost of ownership
Application :
The CRIUS®4.0 is currently used in a multitude of applications and the remote access capability is bringing solutions to our customers’ water treatment requirements.
The CRIUS®4.0 is preferred in the Swimming Pools market, where the superior control and sensor capability provides for better quality bathing water. Again the remote access is proving essential to our customers along with the Variable Speed Drive (VSD) control which is massively reducing electricity usage and CO2 emissions (and reduces the electric bills!).
In the municipal drinking water market, the superior control capability is making it the controller of choice for areas like coagulation control with the superior sensors in use particularly for chlorine control and dissolved oxygen control.
In the industrial market the self cleaning options allow the CRIUS®4.0 to be used for applications that weren’t previously accesible such as in vegetable washing, paper and pulp and meat processing applications.
Summary of Applications
- Water Treatment
- Drinking Water
- Waste Water
- Industrial Water
- Food and Drink
- Pool and Spa Control
- Paper and Pulp
The CRIUS®4.0 can also come in a multitude of languages making it suitable for use in any market.
Customers requiring a no-frills controller should consider the CRONOS® controller.
