Comet T4111 – Temperature Transmitter with 4-20mA Output

• Temperature transmitter for Pt1000/3850ppm sensor with 4-20mA output for two-wire connection is built in a durable watertight case
• Output temperature range is user adjustable
• Degrees Celsius and Fahrenheit are user selectable
• Display is possible to switch off
• Computerized design ensures long term stability and fails indication

Programmable transmitters and transducers with 4 – 20 mA or 0 – 10 V outputs are designed to measure temperature, relative humidity, and barometric pressure in a non-aggressive environment. Transmitters and transducers are available in wall-mount, duct-mount, and bar versions or with a probe on a cable. For measuring temperature and relative humidity of compressed air is used type TxxxxP.

Digital conception with microprocessor allows determining the other computed humidity values, like dew point temperature, absolute humidity, specific humidity, mixing ratio, and specific enthalpy. Measured and calculated values are displayed on a two-line LCD display. Using TSensor software.

Durable plastic case from ABS contains electronic and connection terminals. For easy connection/disconnection of the output, cable is used TxxxxL version with Lumberg connector (IP67) instead of a cable gland.

Applications Measuring and Control of Temperature at:
