The New Festo SPAU Pressure Sensor Lowers OEM Inventory Overhead and Decreases Installation Time

Offering fewer part numbers, a lower list price, and higher functionality compared to the unit it replaces, this new flagship pressure sensor from Festo is arguably the highest value machine and cell level pressure sensor on the market.

HAUPPAUGE, NY, (December 1, 2015) — Festo introduces its new machine and cell level flagship pressure sensor, the SPAU. In terms of functionality and value to OEMs and end users, the SPAU exceeds the SDE-1 pressure sensor it replaces. The SPAU even has a lower list price than the SDE-1 because of advanced design processes, inherent functionality, and the fact that fewer variations had to be engineered and manufactured, thus reducing internal overhead at Festo.

Since fewer part numbers cover more options, compared to the SDE-1, OEM inventory requirements will be lower. Applications for the SPAU include network monitoring (pressure present), regulator monitoring (pressure in the target area), vacuum (partial suction), air-pressure test (pressure drop over time), and object detection (backpressure present).

The extensive options of the SPAU product line include 13 individual pressure ranges, five ways of mounting the unit, and nine ways of connecting the unit to the pneumatic system. Versatility, yet fewer part numbers, results from switchable electrical outputs: PNP, NPN, normally closed, normally open digital outputs as well as current, and voltage analog outputs.

Display and non-display units are available
Lower cost units for basic operation, those without a display, transmit pressure values via analog signal. SPAU units with a display allow users to visually read pressure and set values at the component level. Display units offer three options for transmitting pressure values: switching signal, analog signal, or via IO-Link connectivity. To communicate operating conditions at the operator level, the display changes from blue to red, giving visual feedback for out-of-set-point operation. OEMs and end users have the choice of displaying pressure in bar, MPa, PSI, and other units. In models without a display, analog value output and pressure switching output are proportional to pressure. For these units, switching output can be displayed on the machine HMI using IO-Link.

The SPAU offers a window comparator feature, allowing users to monitor both minimum and maximum pressure with one digital output. Analog outputs can be smoothed by an adjustable internal filter, freeing the PLC from this task. Of special interest to OEMs is a unique feature allowing programmed sensors to instantly replicate their settings to additional sensors, saving significant time during the commissioning phase.

The benefits of IO-Link
IO-Link functionality enables serial communication for both types of sensors - those with or without displays. Analog process values are provided digitally. Sensor parameters can be set and maintained remotely using IO-Link. Parameters are automatically set on replacement sensors via IO-Link and there is no need to repeat commissioning after changing sensors. This not only saves time but also reduces the risk of error.

To speed up installation, units can be equipped with integrated Quick Star fittings, as well as male or female threads to support a wide variety of mounting applications. SPAU sensors are also compatible with H-rail mounting, front panel mounting, mounting brackets, and wall mounting.

Universal Robots - Collaborative Robot Solutions

Universal Robots is a result of many years of intensive research in robotics. The product portfolio includes the UR5 and UR10 models that handle payloads of up to 11.3 lbs. and 22.6 lbs. respectively. The six-axis robot arms weigh as little as 40 lbs. with reach capabilities of up to 51 inches. Repeatability of +/- .004" allows quick precision handling of even microscopically small parts. After initial risk assessment, the collaborative Universal Robots can operate alongside human operators without cumbersome and expensive safety guarding. This makes it simple and easy to move the light-weight robot around the production, addressing the needs of agile manufacturing even within small- and medium sized companies regarding automation as costly and complex. If the robots come into contact with an employee, the built-in force control limits the forces at contact, adhering to the current safety requirements on force and torque limitations. Intuitively programmed by non-technical users, the robot arms go from box to operation in less than an hour, and typically pay for themselves within 195 days. Since the first UR robot entered the market in 2009, the company has seen substantial growth with the robotic arms now being sold in more than 50 countries worldwide.
