Transmitters monitor temperature and
signal
Moore Industries' THZ2 and TDZ2 temperature and signal transmitters can be interrogated and configured with a Hart Communicator, Hart-based control system, or a PC, laptop or tablet PC.
The THZ2 and TDZ2 family of two-wire, loop-powered Smart Hart temperature and signal transmitters from Moore Industries International have input-to-output analogue accuracy up to +/-0.014C The 4-20mA temperature output signal also has a superimposed Hart digital signal, which allows any Hart-compatible control device to program zero, span, sensor trim offset and other calibration variables, and to interrogate and read multiple real-time process variables

System provides secure wireless connectivity
Moore Industries' WLM employs frequency hopping spread spectrum technology and 32-bit CRC error correction for secure, robust communications.
Flexible sensors save time and money
The Worm sensor slides through the enclosure's entry port, and snaps into place without removal of the enclosure, rigid conduit, connection head or any assembly components.
Up to 15 transmitters can be linked via a single twisted-pair wire.
The THZ2 and TDZ2 can be field-configured to accept 14 RTD types, nine thermocouple types, current and voltage signals, resistance and potentiometer devices, and direct millivolt sources, minimising the need to stock spares.
The transmitters can be interrogated and configured with a Hart Communicator, Hart-based control system, or a PC, laptop or tablet PC equipped with software from Moore Industries.
Each transmitter comes with free PC configuration software and a cable.
Both the THZ2 (blind devices) and TDZ2 (with displays) models have 20-bit input resolution for digital accuracy of +/-0.1C with all Pt RTDs, or up to +/-0.05C for Pt1000 RTDs.
THZ2 models are available in encapsulated "hockey puck housings", field-mounted enclosures and DIN-rail field mount housings.
TDZ2 models are available in a "hockey puck" housing or a field-mount housing, with digital displays.
Options include RTD and thermocouple sensors, thermowells, connection heads and fittings.
All models work in temperatures from -40 to 85C and relative humidity of 0-95%, and have RFI/EMI immunity, common mode noise rejection, a digital input filter, burnout protection and output current limiting.
Field-mount models have factory mutual (FM), ATEX, cFMus (US/Canada), IECEx, CSA, Cenelec/Atex 94/9/EC Directive and TestSafe (Australia) approvals for intrinsically safe, non-incendive, explosion-proof and flame-proof operations in Class 1, Division 1, Groups A, B, C and D.
They also have Nema 4X and IP66 ratings, and are CE-conformant.
