Finder.jpg

Finder has announced additions to its 18 Series of PIR motion detectors supporting a variety of interior energy saving schemes.  The compact 18.21 and 18.31 variants will meet the needs of higher ceiling, higher load switching applications and those requiring direct interface to a PLC or BMS.

Recess mounted, the flush fitting 18.31 suits suspended or plasterboard ceilings while the 18.21 is a low profile PIR for hard surface mounting.  Providing a 10 amp rated normally open volt free output, the detectors will switch loads at any voltage and are not restricted to 230VAC mains tasks.  24V ac/dc supply versions are also available for applications without a mains supply or where safe, low voltage operation is required.

With a 110º wide sensing angle and a reach of 2.8m, the 18.21-0300 and 18.31-0300 PIRs will handle all types of regular ceiling height applications.  For high bay or extended ceiling height duties, the 18.31-0031 PIR variant offers a much longer sensing range of up to 8m.

The Finder PIRs also offer an adjustable light threshold setting allowing operation to be varied according to ambient light conditions.  In addition, an enhanced light-on time adjustment of up to 35 minutes makes the PIRs well suited to HID lamp applications, which for reasons of preserving lamp life, place a restriction on the number of starts per hour.

Logo.jpg

Wireless Technology Eliminates the Need for Communications Cabling or Power Line Installation, Saving Time and Money

Honeywell’s XYR6000 Wireless Position Sensor is based on one of the company’s most-proven sensor technologies. The XYR6000 position sensor helps improve overall reliability by giving users the ability to remotely monitor a number of applications ranging from valve position to safety shower emergency use.

Originally introduced by Honeywell Process Solutions (HPS) in June 2009, the XYR6000’s broad spectrum of potential is now being offered by Honeywell Sensing and Control to targeted OEM customers.

Based on the MICRO SWITCH™ CX hazardous area switch, the XYR6000 Wireless Position Sensor monitors position when used in conjunction with OneWireless™ systems, sending the signal from remote or potentially hazardous areas. Featuring full UL, ATEX, and IEC Ex approvals, the XYR6000 Series has calibration within 270 degrees rotation to apply in most linear and/or rotary position sensing applications. Its analog output provides true position span output in both percentages and degrees.

In addition to eliminating manual monitoring, the sensor’s accuracy improves safety by identifying linear or rotary valve positions, minimizing the risk of unwanted fluid release or unplanned product contamination. When used for safety shower notification, the sensor can serve as an emergency response trigger. The XYR6000 Wireless Position Sensor also simplifies maintenance by electronically tagging each valve in the system by identifying valves that have degraded or been damaged. This reduces the need for field technicians to manually inspect valves for maintenance.

Since the sensor carries all the appropriate hazardous location certifications, it is often ideal for applications such as monitoring valve position status, manual process valve position, safety shower and eye bath notification, tank overflow alarms, damper and louver position, gate/door position, and other applications where installing wires is inefficient, cost prohibitive, or simply unsafe.

Honeywell Introduces It's SMART POSITION SENSOR, The Most Accurate and Durable Linear Position Device Available In The Industry Today

Logo.jpg

75mm Linear Position Sensor Offers Unparalleled Performance,Environmental Robustness, and Ease of Installation

Honeywell introduces the SMART Position Sensor, 75 mm Linear Configuration, the most accurate linear position sensor available in the industry (0,05 mm [0.002 in]), enabling highly accurate motion control, and improving operation efficiency and safety. Its simple, non-contact design eliminates mechanical failure mechanisms, reducing wear and tear, improving reliability and durability, and minimizing downtime.

“SMART” stands for Superior Measurement, Accuracy, Reliability, and Thinking. The SMART Position Sensor can essentially think for itself. It uses a patented combination of an ASIC and an array of magnetoresistive (MR) sensors to determine the position of a magnet attached to a moving object.

“The SMART Position Sensor is a revolutionary way of detecting linear position,” said Allen Han, Vice President, General Manager of Sensing and Control’s Electronic Sensing group. “The debut of this sensor provides our customers with the highest level of accuracy, durability, and performance as compared to other equivalent products available today.”

Sealed packaging allows robustness in most harsh environments such as shock, vibration, extreme temperatures, salt water, and dusty or rough terrain. Installation is simplified to four simple steps versus up to 14 steps for some competitive products,reducing set-up costs.

The SMART Position Sensor replaces multiple sensor and switch components that competitive products often require, eliminating extra wiring, connections, and external components, therefore reducing design, installation, and supply chain complexity. Its builtin redundancy and self-diagnostics provide additional safety benefits and reduce equipment downtime.

For design engineers, the SMART Position Sensor provides design and interface flexibility because of its air gap of up to 3,0 ± 2,5mm [0.118 ± 0.098 in] between the sensor and the magnet, and a variety of output options (analog standard; CAN bus and RS232 interface available). The device also has electronics on-board, making it easily adaptable to most commercial platforms, eliminating the need for additional external electronics. Because it offers stable, temperature compensated output, designers do not need to expend engineering resources to build their own output algorithms, reducing total cost of ownership.

The SMART Position Sensor, 75 mm Linear Configuration, may potentially be used in:

*  Industrial applications such as machinery (e.g., cutting and slitting, material  handling, packaging, plastic molding, wafer handling, woodworking), elevators, and industrial flow control (e.g., valve positioning for food and beverage plants)
*  Aerospace and defense applications such as aircraft ram door control and military vehicle suspension arm positioning
*  Medical applications such as imaging, hospital hardware, and syringe pumps
*  Transportation applications such as agricultural combine motion control and crane
   arm positioning.
