Temperature Transmitter and Accessory Selection
The following products are suitable for various temperature measurement applications, including iTEMP series transmitters, TA series terminal boxes, and accessories such as Commubox. During selection, comprehensive consideration must be given to the application environment, output signal, and certification requirements.
TA20A/TA20B Terminal Boxes
- TA20A: Aluminum with epoxy resin coating, maximum ambient temperature +100°C (+95°C under ATEX). Used for installing measuring inserts with head-mounted transmitters or connection sockets. Can be mounted on a bracket or protective sleeve. Product is being phased out; supply is limited.
- TA20B: Black polyamide material, maximum ambient temperature +80°C, protection class IP65. Also used for installing measuring inserts or connection sockets.
Both terminal boxes are suitable for installing measuring inserts and head-mounted transmitters. During selection, attention must be paid to temperature range and material differences.
Commubox FXA195 and Readwin 2000
- Commubox FXA195: USB-to-HART modem, used to connect HART field devices to a computer for commissioning with software tools. Can be connected to intrinsically safe signal circuits, compliant with SIL2 (IEC61508).
- Readwin 2000: Operating and reading software for device configuration and data logging.
Used together, they enable convenient configuration and monitoring of HART devices.
iTEMP Head Transmitter Series
The iTEMP series offers a variety of communication protocols and input types to meet different application requirements. The following is a comparison of key parameters for each model.
| Model | Input Type | Output/Protocol | Special Features | Mounting Type |
|---|---|---|---|---|
| TMT180 | RTD | 2-wire 4-20mA | PC programmable, fault response NAMUR NE 43, UL certified | B-type head, DIN EN50446 |
| TMT181 | RTD, TC, Ohm, mV | 2-wire 4-20mA, electrically isolated | PC programmable, fault response NAMUR NE 43, UL certified, product being phased out | B-type head, DIN EN50446 |
| TMT182 | RTD, TC, Ohm, mV | 2-wire 4-20mA, HART, electrically isolated | Fault response NAMUR NE 43, UL certified, product being phased out | B-type head, DIN EN50446 |
| TMT84 | Dual sensor input, RTD, TC, Ohm, mV | PROFIBUS PA Profile 3.02 | Advanced diagnostics, sensor monitoring, electrical isolation 2kV, current consumption 11mA | B-type head, DIN EN50446 |
| TMT85 | Dual sensor input, RTD, TC, Ohm, mV | FOUNDATION Fieldbus | Advanced diagnostics, sensor monitoring, electrical isolation 2kV, current consumption 11mA | B-type head, DIN EN50446 |
| TMT82 | Dual universal sensor input, RTD, TC, Ohm, mV | 2-wire 4-20mA, HART | Electrical isolation 2kV, drift detection and sensor backup, optional SIL2/3 (IEC61508) | B-type head, DIN EN50446 |
Selection Tips: TMT84 and TMT85 support dual sensor inputs and advanced diagnostics, suitable for applications requiring high reliability; TMT82 supports HART communication and SIL certification, suitable for safety instrumented systems. TMT180/181/182 are earlier models, some of which have been phased out. It is recommended to prioritize the TMT82/84/85 series.
TXU10 Configuration Kit and TID10 Display Unit
- TXU10: Configuration kit for PC-programmable devices, including setup program and PC interface cable with USB port.
- TID10: Plug-in display unit, dot-matrix measured value display, with 12 DIP switches at the bottom for setting FF (simulation, write protection) or PA (bus address, write protection). Compatible with TMT85, TMT84, TMT82, TMT71, TMT72.
TXU10 simplifies the transmitter configuration process, while TID10 provides on-site display and quick setup functions.
TA30A/TA30D Terminal Boxes
- TA30A: Used for installing terminal blocks or head-mounted transmitters and optional displays. Low-profile hinged cover, optional window. Aluminum housing, polyester powder coating, blue body, gray cover. Ambient temperature -50...150°C, protection class IP66/68, NEMA 4X.
- TA30D: Used for installing 2 head-mounted transmitters or terminal blocks. High-profile hinged cover. Material and coating same as TA30A, ambient temperature -50...150°C, protection class IP66/68, NEMA 4X.
The TA30 series terminal boxes are rugged and durable, suitable for harsh industrial environments. TA30D can accommodate more transmitters, saving installation space.
