GP-MC – Multi Purpose Data logger

Product Details

Description

The GP-MC is a high resolution (12 bit) multi purpose data logger with eight analogue and two digital pulse inputs. It also provides a Start on Trigger input and two alarm outputs. The GP-MC can be supplied in an optional seahorse IP66 Weatherproof enclosure if required. It can be configured to accept input from a wide variety of sources including:

The GP-MC also has an internal temperature sensor for convenient logging of ambient temperature if desired.

One to Five year battery life depending on usage as below, user replaceable. Data is retained in the event of battery failure. Battery Status Monitor in Omni7 Software.

• Warning: When using the Average, Maximum or Minimum reading(s), the logger reads the attached sensor(s) every second. This will reduce battery life.
• Using the logger in temperatures below -5°C (23°F) will reduce battery life.

A DLC5USB [USB] download cable (2m) is required to connect the GP-MC to a computer.

Note: GP-MC inputs are individually configurable using Omni7. Each input requires conditioning using a ‘Probe Set’ – see example picture below:

External Power Input:

The GP-MC has an internal battery which powers the logger and probes. However, it can also be powered by an external 5V to 15V DC Plug Pack or Battery. The main reasons for using the External power input are:

• When large current draw from probes would flatten the Internal battery; and
• At very low temperature (< 10ºC) where the Internal battery voltage can drop.
• External power can also be used to run the logger while the internal battery is changed.

The Internal battery runs the logger if the External power fails. There is an External Power Status Monitor in Omni7 software.

Please note that Intech Instruments’ recommends the internal battery be left in place in case the external power supply fails. The internal battery will keep the logger going should this happen. More information below:
If the logger is run with no internal battery and the external supply fails the logger will turn off. When the external power supply is turned back on, the logger will reboot and will be in “Stopped” mode. The logger will need to be configured in “start on condition” mode and “loop” mode and the “Start Logger” button clicked to initialise the next recording cycle.
It is recommended that the internal battery is left in. No power is drawn from the internal battery unless the external supply fails and the internal battery will keep the logger running during the down time. The logger will stay on standby and start on condition even if the external supply is still down.

* Logging Thermocouple inputs with the GP-MC:

A lot of people say thermocouple to mean temperature probes, where as if the temperature range they are measuring is between -50°C and +200°C, then RTD Pt1000 is more accurate and cheaper to implement than thermocouple. The GP-MC accepts RTD Pt1000 input (with the necessary resistors). Thermocouples are ideal for high temperature ranges.

The only way that the GP-MC can accept a thermocouple signal is via an intermediary transmitter like the XU Series with an output signal of 4~20mA.mA-MC-PS input cables for each input from the XU Series transmitter(s) into the GP-MC are also required.

The Tc-HR or Tc-LCD data loggers are available for logging 1x Thermocouple input.
