Main Applications: Radio Frequency Sensors

About Wireless Sensors

No need to run wires throughout your facility—these wireless sensors are easy to set up and allow you to monitor noncritical processes from your PC. All are battery operated with a microprocessor-controlled, 418 MHz, FCC-certified radio transmitter and built-in clock (unless noted). At selected time intervals, the clock "wakes" the microprocessor that has been waiting in a dormant state to receive your digital data. The data is read by the sensor, combined with a send/receive error check, and then transmitted to your receiver and PC in just 15 milliseconds. This process consumes very little energy, which means sensor batteries can last up to five years. To create your own wireless sensing system, you'll need a wireless sensor, a wireless receiver, and a PC. Simply set up the sensor at your desired location, connect the receiver to your PC, and you're ready to go. If you already have a sensor with a 1-5 VDC, 5-10 VDC, or 4-20 mA output, just add an input transmitter to your sensor so it can wirelessly transmit data to your receiver. To extend the range of your sensing system, just add a repeater(s) between your sensor and receiver.

Wireless Sensors

No need for an external power source, these sensors have a battery, internal antenna, and built-in transmitter to wirelessly send data to your wireless receiver (not included) at specified transmission rates. Up to 100 sensors can be used with a single receiver. All are made of ABS plastic, have a water-resistant coating for wet environments, and measure 2.1" Lg. x 1.3" Wd. x 0.6" Ht. They comply with part 15 of the FCC rules.

Wireless Input Transmitters

Wirelessly transmit data to a wireless receiver (sold separately on this page) by adding one of these transmitters to your 1-5 VDC, 5-10 VDC, or 4-20 mA output sensor. They operate on 418 MHz and have a transmission rate of 10 to 240 seconds at a range of up to 600 feet. Up to 100 transmitters can be used with a single receiver. All include an internal battery, are ABS plastic with a water-resistant coating, and measure 2.1" Lg. x 1.3" Wd. x 0.6" Ht. They comply with part 15 of the FCC rules.

	Each
1-5 VDC	$174.33
5-10 VDC	$174.33
4-20 mA	$174.33

Wireless Repeater

Extend the transmission range of your wireless sensors and input transmitters with this wireless repeater. It receives at 418 MHz from up to 600 feet and transmits at 900 MHz from 600 to 1300 feet indoors and up to 7 miles outdoors. Includes a 6-ft. long power cord.

Each: $575.98

 

Wireless Receivers

Here's what you need to receive and decode digital data from all of the wireless sensors and input transmitters sold separately on this page. Once the receivers gather the data from your sensors and input transmitters, they send it serially to your PC so you can display, manipulate, analyze, or store the information. Receivers operate on 418 MHz (unless noted) and accept signals from up to 100 sensors and input transmitters. Standard receiver is powered by your serial port; others include a 6-ft. long power cord.

Standard receiver is the simplest companion for our wireless sensors and input transmitters. Includes computer software.

Mobile receiver can be moved throughout your facility, or even attached to a laptop computer.

Web-enabled receiver allows you to view and manipulate your data over the internet.

Data-logging receivers allow you to store data in the internal log memory.
