The DLP/MLP2 Series are based on a piezoresistive, silicon sensing element which senses Differential Pressure and provides an analog output.
New PI-Based Products to Celebrate Pi Day
In honor of Pi Day, we’re celebrating the Raspberry Pi, which was created by the Raspberry Pi Foundation as a way to make computers more accessible to people all over the world. The Foundation provides low-cost, high-performance computers so more people are “capable of understanding and shaping our increasingly digital world, able to solve the problems that matter to them, and equipped for the jobs of the future,” (Source: www.raspberrypi.org/about/).
Contemporary Controls strongly supports the vision of using open hardware and software to make technology more accessible to everyone. As part of our vision for open control, we’ve created products that leverage the Raspberry Pi. We chose the Raspberry Pi because it is a powerful embedded platform, it is easily accessible, and it is the micro PC with the largest community which provides support in the form of custom applications, software tricks and neat “hacks”. Given that the community already has a lot of diverse applications for the Raspberry Pi, we wanted our products to offer new capabilities.
Control Without Restrictions
The BASpi I/O board turns your Raspberry Pi into a BACnet-networked, Sedona-programmable controller with 6 Universal Inputs and 6 Relay Outputs. The BASpi hat provides enhanced hardware circuitry, web-based configuration, and free graphical programming software for control applications. We wanted to truly enhance the capabilities of the Raspberry Pi3. We also wanted to keep both the hardware and software open, so we designed our BASpi hat so it can be run in conjunction with other applications on the Raspberry Pi.
Combined with our BASpi hardware and software tools enhancements, the already powerful Raspberry Pi3 turns into an extremely capable control device with web based configuration, universal IO, and industry standard data communication and control protocol – BACnet.
We’ve created two versions of the BASpi. One is just our BASpi I/O board for those people who already have a Raspberry Pi and are experienced with programming it. The other is the entire system, which includes the Raspberry Pi 3 board, our BASpi I/O board, an industrial grade μSD card with pre-written image, international power supply, and an enclosure case.

Open Control Meets Micro PC
Our soon-to-be released BASpi BACnet Client Controller turns an already powerful micro PC, Raspberry Pi, into a BACnet client and open Sedona controller. It serves as a mini-supervisor to BACnet/IP server devices over Ethernet or Wi-Fi and BACnet MS/TP devices over EIA-485. Using custom Sedona network variable components, the BCC can initiate read/write commands from its Sedona wire sheet to BACnet/IP or BACnet MS/TP server points on remote devices. Server points need not be Sedona compliant – just BACnet compliant. Any BACnet remote I/O such as Contemporary Controls’ Cube I/O can be made into a freely-programmable controller with the addition of the BCC. More information about the BASpi BCC coming soon.
We aren’t done yet — stay tuned for more products based on the Raspberry Pi in the near future.

Monitoring differential pressure with ACI’s A/WPR2 is a great first step in saving energy with an efficient flow system. According to some estimates, pumps account for between 10% and 20% of world electricity consumption. Unfortunately, many pumps use more energy than necessary due to inefficient flow control. Varying a pump’s speed using a variable-frequency drive (VFD) on the pump motor based on the differential pressure in the system is an efficient method to control flow and save energy. Using a VFD with your pump motor is most effective in saving energy when accurate and reliable differential pressure information is provided. The tighter your control, the more efficient your system and the more energy and money you save.
Features of the WPR2:
• Field Selectable • Field Selectable Outputs: 4-20mA, 0-5VDC, 0-10VDC
• Optional Display
• Remote Probes (no extra plumbing or 3-valve manifold necessary)
• Accuracy: +/- 1.0% FSO • Auto Zero Button
The newly announced CIPer™ Model 30 Controller from Honeywell offers many features, but BACnet MS/TP device control is presently unavailable. At the recent Momentum conference, during the session on new controllers, the Honeywell presenter suggested that the Contemporary Controls BASrouter should be used by customers seeking this functionality with the CIPer 30.
The BASrouter (BASRT-B) is a BTL Listed compact BACnet multi-network router, which provides versatile stand-alone routing between BACnet/IP, BACnet Ethernet, and BACnet MS/TP networks. Installing and operating the DIN-rail mounted BASrouter is simple and straightforward. Once the BASrouter is properly installed and configured, all the MS/TP devices can be accessible from BACnet/IP.
The BASrouter is powered from a 24 VAC/VDC source that can be shared with other devices in some situations. It requires about 4VA of power. There is one MS/TP port and one 10/100 Mbps Ethernet port. The MS/TP port offers an optically isolated transceiver that is compatible with both two-wire non-isolated MS/TP networks or three-wire isolated networks. Internal MS/TP bias and termination is provided but can be disabled via internal jumpers if needed. The BASrouter consumes one EIA-485 load and can drive 31 full-load devices (or even more partial-load devices) although a network limit of about 45 devices is recommended to improve responsiveness. The BASrouter is designed for near end installation. Mid-span installation is possible but should be avoided.
The Ethernet port offers a shielded RJ-45 connector. Auto-negotiation and Auto-MDIX allows this port to automatically match connections to the attached equipment. Therefore, either straight-through or crossover CAT5/6 cable can be used for connection to the network. A resident web server allows for commissioning and troubleshooting using a standard web browser. We are now exclusively shipping the BASrouter Version 3.0, which provides enhanced diagnostic capabilities with visual analytics. Diagnostics include a graphical MS/TP status table, routing status table, network errors count, and traffic statistics. These new features allow an integrator to install a robust BACnet network with ease.
