Product Details

The Pt-LCD is a high resolution (16 bit), handheld temperature data logger with a liquid crystal display. The logger connects to an external RTD probe and also has an internal temperature sensor for convenient logging of ambient temperature if desired.

The logger accepts RTD Pt100, Pt500 and Pt1000 probes. The display shows the RTD temperature, logger internal temperature, battery voltage, logger and alarm status.

This logger is designed for indoor use (IP 40) but can be supplied with a Seahorse Logger Enclosure for outdoor use.

Features

  • 6 pin Connector Socket can be used to connect to 2 wire, 3 wire and 4 wire. RTD Pt100, Pt500 and Pt1000 temperature probes.
  • Storage capacity of over 500,000 samples.
  • Easy to use LCD menu options.
  • LCD display shows logger status and alarm status continuously.
  • LCD display can be set to show; RTD temperature, internal temperature, battery voltage, number of logged samples and alarm status.
  • Temperature can be set to any combination of Point, Average, Maximum & Minimum readings.
  • The battery voltage of the logger can be logged if required.
  • The logger can be run in either “Stop when memory is Full”, “Loop Around” mode or set to stop at a future time.
  • The logger can be started “Now”, at a given time in the future, on a condition (e.g. temperature >20ºC) or on Trigger (push button on logger)

Alarms Two independent Alarms
Triggered on any combination of six user configurable Alarm Conditions
Both alarms can be configured to send SMS messages if connected to a cell modem
Two Open Collector Alarm Outputs
Alarms can be visually checked on the LCD Display or by using the Omni7 software
Start modes Start immediately; Start on date/time; Start on Condition (e.g. temperature >20ºC);
Start on trigger (push button on logger)
Stop modes Stop when memory is full / Stop on date/time / Loop around (continues logging)
Logging modes Each channel can be set to log any combination of:
– Point readings          – Average reading
– Maximum reading     – Minimum reading
Warning: When using the Average, Maximum or Minimum reading(s), the logger reads the attached sensor(s) every second. This will reduce battery life.
Battery One to Five year life depending on usage as above
Using the logger in temperatures below -5°C (23°F) will reduce battery life
