SECOND GENERATION COMPACT INFRARED ARRAY SENSORS LAUNCHED
HIGH PERFORMANCE PRESSURE
TRANSMITTERS
New from TT Electronics is the TPM Series of high-performance industrial pressure transmitters.
These have a stainless steel housing and feature digital compensation to provide accurate and reliable pressure measurements with excellent long-term stability over a temperature range from -20˚ to +125˚C. Features include a 4-20mA output that is proportional to the pressure directly detected by a four-arm, active strain-gauge bridge, which is formed from highly stable resistors fused to a high purity ceramic pressure-sensing element. Internally, the electronic elements comprise a primary signal processing module that utilises an ASIC-based highspeed digital signal processor and a separate board that handles the interface and EMC immunity and emissions requirements. All elements of the TPM combine to ensure a ±0.1% span non-linearity, hysteresis and repeatability specification (BFSL) over the full operating temperature range, together with excellent long-term stability (±0.1% span/12 months typical). Applications are in hydraulic and
pneumatic systems, fuel and lubricant pressure sensing, leak detection, filter testing and tank level sensing.

The improved second generation of Panasonic Automotive & Industrial Systems Europe’s Grid-EYE infrared array sensors have now been launched. These are fully compatible with the existing first generation designs. The new high gain types
(AMG8833 and AMG8834) and low gain types (AMG8853 and AMG8854) of Grid-EYE 2nd Generation now benefit from an improved NETD (Noise Equivalent Temperature Difference) of 0.16°C at 10Hz and of 0.05˚C at 1Hz. In addition, the detection distance has improved from 5m up to 7m. According to the company, the new sensors
combine a more sensitive MEMS sensor chip, a digital ASIC (I2
C interface) and a silicon lens in a
compact package. In addition, the parts feature 64 thermopile elements in an 8x8 grid format that detect absolute surface temperature without any contact. Grid-EYE uses a patented 60˚ silicon lens etched out of a silicon wafer with a height of 0.3mm. The combination of these technologies allows for a sensor package size of only 11.6mm x 8mm x 4.3mm. The new generation can not
only detect moving and motionless people
and objects, but is said to do it with higher precision and higher accuracy than its predecessor.

ACCESS DETAILED SENSOR DIAGNOSTICS IN HARSH ENVIRONMENTS
With the IP67 rated Allen-Bradley ArmorBlock IO-Link master from Rockwell Automation, manufacturers and industrial operators can now access more detailed sensor diagnostics in harsh operating environments. The new IO-Link master stores up to 40
timestamps of sensor events on each channel, enabling users to track changes and diagnose issues more easily. Input timestamps of all sensor data can also be sent to the controller upon a change of state. According to the company these, and other diagnostics available through the device, can reduce issue-resolution time by as much as 90%, improve preventive maintenance and optimise overall system performance. The ArmorBlock IO-Link master includes connectivity for up to eight IO-Link sensors. The
master and sensors share an IP address, helping end users reduce the cost and time taken to commission equipment.

RADAR LEVEL SENSOR WITH BLUETOOTH COMMUNICATIONS NOW COMES WITH EX APPROVAL
VEGA Bluetooth communications have been a standard option across the whole range of plics transmitters since March. This features secure 64 bit encryption and pairing using Apps or a PC USB dongle via PACTware. Until now, however, this has only been available for safe area devices. A new option has, however,
now been introduced for the 80GHz radar level sensors
8 SEPTEMBER 2016 | INSTRUMENTATION
VEGAPULS 64 (liquids) and 69 (bulk solids) –ATEX / IECEx: Ex ia, Ex ia/t (Dust) FM: OL, XP, DIP approvals. This enables the easy set up and sensor management using EX capable tablets and smartphones, run by Android, with Bluetooth 4.0 via the VEGA TOOLS App. They can also be operated via a magnetic pen through a window. According to the company, this
option means ‘hot work’ permits may not be needed, as no covers are removed or wires connected to sensors or signal cables. Engineers can work from safer locations, possibly even outside clean rooms in electronics, pharma and food industries, saving time and increasing safety.

THERMAL ENERGY HARVESTING ADDED
TO WIRELESS RANGE Emerson is using advanced thermal energy harvesting as a power source for its wireless products. Power Puck thermoelectric energy harvesters convert ambient heat commonly released in industrial processes into electricity for powering Rosemount wireless transmitters. The Power Puck thermoelectric
energy harvester provides continuous, reliable, power for the life of the transmitter and includes an intrinsically safe power module for back-up power. According to the company,
Perpetua’s Power Puck energy harvesting solution is said to be especially advantageous to wireless devices in power intensive applications.
