SITRANS TF is made of rugged die cast aluminum or long-lasting stainless steel. It transforms resistance thermometers, thermocouples, Ohm and mV signals into a load independent DC current corresponding to sensor characteristic or a digital signal according Fieldbus standard Profibus PA or Foundation Fieldbus. The remote mounted sensor prevents the transmitter heating up at high temperature; there are no vibrations and oscillations due to long neck tubes and protective pipes with SITRANS TF.

For tags with difficult access to you can mount your SITRANS TF remotely at easily accessible places and display the measured value on the freely programmable digital display (with version 4 to 20 mA).

You can even use the SITRANS TF in a version without a transmitter as a comfortable field display unit for all 4 to 20 mA signals.
All SITRANS TF are available in intrinsically safe or explosion proof version

Benefits

• Universal use
  • as transmitter for resistance thermometer, thermocouple element, Ω or mV signal
  • as field indicator for any 4 to 20 mA signals
• Local sensing of measured values over digital display
• Rugged two-chamber enclosure in die-cast aluminium or stainless steel
• Degree of protection IP67
• Test terminals for direct read-out of the output signal without breaking the current loop
• Can be mounted elsewhere if the measuring point
  • is hard to access,
  • is subject to high temperatures,
  • is subject to vibrations from the system,
  • or if you want to avoid long neck tubes and/or protective tubes.
• Can be mounted directly on American-design sensors
• Wide range of approvals for use in potentially explosive atmospheres. “Intrinsically safe, non-sparking and flameproof” type of protections, for Europe and USA.
• SIL 2 (with order supplement C20)

SITRANS TF can be used everywhere where temperatures need to be measured under particularly adverse conditions, or where a convenient local display is ideal. Which is why users from all industries have opted for this field device. The rugged enclosure protects the electronics. The stainless steel model is almost completely resistant to sea water and other aggressive elements. The inner workings offer high measuring accuracy, universal input and a wide range of diagnostic options.

The RHT-WM and RHT-DM transmitter series incorporate the best high accuracy and great stability relative humidity and temperature sensors. They convert the measured values into linear 4 to 20 mA signals. The microprocessor based circuit enables full configuration of output range when used with the TxConfig PC interface and the Windows® based software.

The humidity signal can be configured to either relative humidity or dew point output. The RHT-WM model is dedicated to wall mounted applications and the RHT-DM version is suitable for duct and through-the-wall applications.

FieldLogger is a versatile, powerful, and yet cost-effective data logger handling analog, digital, and other types of variables with high resolution and speed. It is a high performance and high connectivity equipment and yet easy to configure and operate.
 
It has 8 configurable analog inputs that can read thermocouples, Pt100, Pt1000, voltage and current signals. It also has 2 relay outputs and 8 digital ports individually configurable as inputs or outputs.
 
Up to 128 mathematical channels can be used to perform operations on the measured values. Up to 32 alarm events can be detected, allowing output activations, e-mails and SNMP traps sending.

Its RS485 interface can operate as a Modbus RTU master or slave. As a master, it can read and log up to 64 external channels. It has a 10/100 Mbps Ethernet interface that allows for access through a browser (HTTP), FTP (client and server), e-mails sending (SMTP), SNMP and Modbus TCP.
 
FieldLogger has one USB interface to be connected to a computer (for configuration, monitoring and data download) and another USB port for plugging a flash driver for data retrieval. The 512k logging basic memory is used to store data and it can be greatly expanded with an SD card.
