F-Series: F143

Field mount - Temperature monitor

with high / low alarms and analog outputs

The F143 is a versatile temperature indicator featuring continuous temperature monitoring. It offers the ability to set two low and two high temperature alarm values. If desired, an ignore function can be set up to allow for an incorrect temperature for a certain period of time. Up to five outputs are available to transmit alarm conditions and actual temperature.
The display shows the actual temperature, alarm values, alarm messages and status. On-screen engineering units are easily configured from a comprehensive selection.

Advantages
  • Robust IP66, IP67 (NEMA Type4X) field enclosure. It is so rugged, you can even stand on it!
  • Intrinsically Safe available - ATEX and IECEx approval for gas and dust applications.
  • Programming can be done by your own crew, with the sensible menu-driven structure, saving cost and irritation. Know one, know them all!
  • Very diverse mounting possibilities: walls, pipes, panels or directly onto outdoor sensors.
Application overview F143

Features

  • Temperature monitoring: four alarm values can be set: low-low, low, high and high-high temperature alarm.
  • Alarm values can be changed by the operator or they can be password protected.
  • Analog output to transmit the actual temperature.
  • Temperature and alarm values: six large 17mm (0.67") digits.
  • Displays temperature, measuring unit and alarm messages simultaneously.
  • Alarm ignore function allows an incorrect temperature for a certain period of time.
  • Selectable on-screen engineering units: °C - °F - K or no unit
  • Up to four configurable alarm outputs.
  • Displays clear alarm messages.
  • LED backlight.
  • Backup of settings in EEPROM memory.
  • Ambient temperature: -40°C to +80°C (-40°F to 176°F).
  • Various accessories are available for this product.
  • The F-Series is so rugged, even a truck can stand on it!

Temperature Inputs

  • (0)4 – 20mA.

Alarm Outputs

  • Function: Configurable alarm outputs for low-low, low, high, high-high or all combined temperature alarms.
  • Type: Up to three passive NPN transistors or active PNP transistors or up to four isolated electro-mechanical relays.

Analog Outputs

  • Function: Re-transmitting the actual temperature - the output can be scaled to any range (e.g. -20°C to +200°C).
  • Type: One passive isolated, floating or loop powered 4 – 20mA output or one active (0)4 – 20mA or 0 – 10V DC output.

Applications

  • The F-Series is your first and best choice for field mount indicators in safe and hazardous area applications. Especially in harsh weather conditions like rain, snow, salty atmospheres and temperatures between -40°C up to +80°C (-40°F up to 176°F).
  • For applications where continuous temperature measurement and monitoring is important. Also signal re-transmission of the actual temperature or serial communication is required.
    Alternative basic models: F040, F043 or the D-Series basic DIN panel mount indicators.

Power Supply

  • Long life Lithium battery.
  • 4 – 20mA Loop-powered.
