Moore Industries THZ WirelessHART temperature solution

The THZ WirelessHART temperature solution combines the Moore Industries THZ Smart HART temperature transmitter and the Bullet WirelessHART adapter by MACTek into one reliable self-powered package.

The updated WL housing includes a battery case using off-the-shelf D-type lithium batteries wired to the transmitter and the Bullet. This means that the package can be installed without the need for potentially expensive signal wiring or additional power. This saves on long-term maintenance and repair costs associated with wiring, along with eliminating the need to stock or purchase special batteries. It also reduces replacement battery costs by cycling the THZ’s power and taking periodic readings to optimise the balance between power needs and wireless communication update rates. This and other features allow the lithium batteries to last up to five years.

The THZ WirelessHART assembly allows the THZ to transmit critical temperature and HART diagnostic information to a WirelessHART gateway in situations where power is not readily available. Examples of this include a remote pumping station or monitoring locations where access to power is limited. By using the THZ WirelessHART solution, engineers can take full advantage of critical temperature readings and HART diagnostics without needing solar panels or other power sources.

The solution also features 20-bit input resolution and long-term stability specifications, with up to five years of service between scheduled calibrations. The Bullet prevents the loss of critical temperature readings by monitoring the battery voltage and setting a HART alarm bit when it nears critical levels.
