Device description
2.1 General description
The TT 51 transmitters are intelligent 2-wire universal transmitters for measurement with up to
two user programmable channels in single, differential, average, minimum or maximum mode.
The transmitters are intended for:
•
Temperature measurements with single or dual resistance temperature sensors
•
Temperature measurements with single or dual thermocouples
•
Temperature measurements with one resistance temperature sensor and one thermocouple
•
Temperature difference measurements with resistance temperature sensors
•
Measurements with potentiometers
•
Voltage measurements in a range -10
…
1000 mV
To increase reliability and stability of the system the transmitters have dual sensor inputs. The
dual sensor inputs enable new safety features such as sensor redundancy and sensor drift
monitoring.
The TT 51 C are designed for installation in a B connection head according to DIN 50446 or
larger.
The TT 51 R are designed for installation on a rail according to EN 60715 / DIN 50022.
Following Ex approvals for the transmitter are available:
•
Standard version: without any Ex approval
•
Intrinsically safe version: TT 51 C for use in areas with potentially explosive atmospheres
(zone 0, 1 and 2)
•
Intrinsically safe version: TT 51 R for use in areas with potentially explosive atmospheres
(zone 1 and 2)
The 2-wire universal transmitters are HART
®
5 and 6-compatible. Configuration of the
transmitter is possible with:
•
HART
®
5 and 6 protocol via 4
…
20 mA output circuit
•
HART
®
5 and 6 hand held terminal
•
The graphic user interface DTM
•
The third part PC software with a FSK modem for HART
®
5 and 6 communication
•
PC configuration software (ConSoft) with PC configuration kit (ICON)
INFORMATION!
The transmitters have a full assessment, performed by SP (Technical Research Institute of
Sweden), according to IEC 61508 part 1 to part 3, for use in SIL 2 rated Safety Instrumented
Systems (SIS). For safety instructions see the separate safety manual.
INFORMATION!
The PC configuration software ConSoft is used for configuration, display and documentation.
The current ConSoft version is available for downloading on our website.
