Built upon the popular A-series and B-series platforms, the A+ and B+ feature Integrated Smart Technology, delivering a range of out-of-the-box benefits and giving OEMs the ability to develop their own custom solutions.
With over 15,000 data slots, A+ and B+ sensors onboard memory comes pre-populated with more than 30 sensor-specific parameters and ample capacity for instrument manufacturers, services houses or end users to add further data, in production or during the lifetime of the device.
A+ and B+ sensors provide instrument manufacturers with the critical sensor data they require and the ability to add more, an innovation with the power to revolutionise production, maintenance and end user experience.
Smarter Sensors, Smarter Production, Smarter Instruments
With Integrated Smart Technology (IST), the A+ and B+ deliver a range of benefits over their standard A and B series counterparts, though crucially sharing the same format, pin-out and sensor characteristics allowing backwards compatibility and interchangeability between models.
With the IST chip flush-fitted within the base of every sensor, the A+ and B+ each have over 15000 built-in memory slots, feature onboard temperature monitoring and interface using robust surface mount spring contacts.
Every electrochemical sensor Alphasense produce is subject to rigourous performance testing. With the benefit of IST, the test and calibration data of each specific A+ and B+ sensor is loaded onto the sensor memory. All IST enabled sensors are shipped pre-loaded with a host of model-specific and sensor specific parameters including; build data, customer data, warranty info, serial number, target gas, performance ranges, and full factory calibration data.
In making factory calibration data readily available, the A+ and B+ simplify integration into instruments in production, with manufacturing systems or the instrument itself gathering the data it needs from the sensor – no scanners, spreadsheets or paper required.
On-sensor temperature monitoring provides manufacturers with data from the immediate vicinity of the sensor, making a critical difference to temperature compensation, particularly in the case of PPB monitoring and detection.
The A+ and B+ are loaded with as much sensor-specific information as is available from the factory, delivering a multitude of benefits. In addition, 8KB of vacant memory gives, OEMs, their distributors or end users to access, add or amend data to the sensor’s memory as required and authorised.
In providing factory calibration data and giving OEMs the ability to upload their own, the concept of plug and play sensors becomes a reality.

Plug and Play, Your Way
With more than 8KB of vacant memory, A+ and B+ sensors present instrument manufacturers with the opportunity to streamline production, improve performance and enhance end user experience.
Working closely with customers and drawing on the experience of our employees who have worked in the instrument world, it’s apparent that there are multitude of ways in which IST can be used to assist instrument manufacturers, distributors and end users, these include;
Pre-calibrated Sensors
The complexities and costs associated with calibration of instruments can be obstructive, both during production and in the field. The transport and handling of calibration gases carries risk and can be expensive and calibration requirements require training and can delay operations.
The ability to pre-calibrate sensors, be that a certified calibration by Alphasense, an instrument manufacturer or an approved maintenance organisation, allows users to plug in a pre-calibrated sensor and go straight to work rather than spending time and resource on calibration.
Traceability / Route to Market
From a corporate responsibility and business management perspective, IST gives instrument OEM’s the ability to add a digital signature to sensors which can be used to trace their route through supply chain. Manufacturers may also wish to use IST to employ a service lock or to code sensors to instruments or docking stations, preventing rogue distributors, the use of 3rd party/uncertified sensors or those sensors procured through unauthorised outlets. In logging instrument operating conditions on the sensor, its possible to identify usage and more closely scrutinise faults and warranty claims.
Maintenance
With end of warranty date and shelf-life expiry date preloaded and the ability to add other maintenance related data, the host device can build an awareness of its own warranty and service status, rejecting sensors it deems out of date or specification. In saving bump and calibration performance data onto the sensor, the device can build up a picture of the condition of each individual sensor. An instrument with enhanced sensor data can drive predictive rather than reactive maintenance, minimising instrument downtime, preventing unnecessary sensor replacements/calibrations and reducing lost working hours.
Performance
The availability of factory test data on the sensor assists manufacturers in more accurately integrating sensors into instruments. With sensor performance limits captured within the sensor memory, the host device can be aware when operating conditions are outside of the sensors range, giving greater insight into alarm activity and enhancing safe operation of devices.
Compliance
The ability to save bump and/or calibration dates on individual sensors ensures that only sensors requiring calibration are tested, saving time and money. With the ability to save performance and calibration data to sensors, an instrument can build up a picture of sensor performance over time, driving predictive rather than periodic bump and calibration.
The use of plug and play sensors can be used to increase fleet compliance and the presence of sensor specific data regarding warranty and service can prevent unnecessary sensor replacements.
Interchangeability
Where sensors for multiple target gases are used in the same device, the host instrument is able to identify the target gas of the installed sensor by accessing its memory, without the need for user intervention. The sensor can also be programmed with alarm set points which the instrument can use to automatically update to the target gas of the sensor.

Developed in the Lab, Proven in the Field
A+ and B+ sensors are built upon the high-performance A and B-Series sensors that Alphasense are recognised for globally. A+ and B+ are available across our full A and B-series with the exception of O2 sensors which are currently in development.
Interchangeability between A+ / B+ and standard A and B series sensors give instrument manufacturers the ability to standardise electronic hardware and offer tiered instrument functionality based upon sensor selection. The base model instrument may for instance feature the A series and the premium product the A+, bringing with it features such as predictive maintenance, plug and play sensors or enhanced compliance management.
