Do you need external power for your Field Units?

No, all of our Field Units are battery powered.

How long does the Battery last?

The battery lasts 2-5 years depending on the user selected sample and transmit rates. A duty cycle that samples and transmits every second yields a battery life of 2 years. Transmitting on average every 5 seconds results in a 5 year battery life.

What wireless protocol do you use?

Accutech uses a multi-vendor industrial wireless protocol that was developed specifically for highly reliable and secure performance in heavy industrial environments.

What is Frequency Hopping Spread Spectrum?

Messages are sent using the entire spectrum between 902 and 928 MHz to talk around any potential RFI. The pattern is varied so that only Accutech equipment knows what frequency is next. Please see Tech Note 219 for a more detailed description.

How many field units can talk to one Base Radio?

You can have up to 100 field units talking to one Base Radio.

How can I get my data into my PLC/DCS?

Accutech has several possible ways to get data into your control system. The most common interface is Modbus RTU from the Base Radio directly to a PLC or DCS. Outputs can also be provided as analog and switch outputs via DIN rail mounted Output Modules. Other digital protocols such as Modbus TCP/IP can be supplied using external converter modules.

What types of measurement devices do you offer in you wireless product line?

Accutech offers RTD and Thermocouple temperature; gauge, absolute and differential pressure; 4-20mA, 0-10V analog, contact closure, and acoustic monitoring with more on the way! Both integral and split sensor options are available.

Do I need an FCC license?

You do not need an FCC license to use these products. Just install and use!

How do I know that Accutech Wireless products will work in my plant?

Accutech sales representatives can perform a site survey at your plant. This consists of using a Base Radio at a possible installation point and walking a field unit to all the measurement points to validate good signal strength for reliable communication.
