TELETRANS Multivariable Smart Transmitters
Like all smart transmitters, TELETRANS uses a microprocessor to provide improved sensor characterization and digital calibration. Basic measurement uncertainty is 0.1% and calibration is easily performed via our Smartkit software on a notebook PC.
Two models are available: DP/P/T and P/T. TELETRANS is particularly advantageous for orifice metering. Purchasing and installing one instrument rather than two or three provides significant cost savings.
While TELETRANS provides a 4 - 20 mA output for the primary variable (DP or pressure), all inputs, plus diagnostic information, are available via the digital link. The standard digital medium uses the same two wires as the analog signal, with frequency shift keyed (FSK) modulation at 1200 baud.
Internal communication options include RS 232 and RS 485 multidrop, at 9600 baud, and a 202/212, 1200 baud modem. The modem can operate in dial-up or private-line modes. With the built-in modem, the transmitter resides on a live SCADA network (not just a local Fieldbus) and effectively replaces a simple RTU with three transmitter inputs. All communication uses the BSAP protocol.
TELETRANS uses an explosion-proof housing and is available in a variety of materials, such as Hastelloy C, Monel, and Kynar in addition to stainless steel. In addition, a PDM input version is compatible with Bristol telemetry systems.
