A fully configurable touchscreen display allows the operator to choose which parameters to display on the CMC-99 controller and data logger and in which graphical format such as chart, bargraph, dials or numeric values. To help with device configuration it is possible to connect a standard USB keyboard and mouse directly to the CMC 99.
The CMC 99 logging controller can provide up to 8 proportional, integral and derivative (PID) control functions along with up to 4 – 8 separate On/Off alarm relays depending on power rating.
The internal datalogging memory of the CMC99 process controller can store up to 250 million samples of data with a 1.5GB memory capacity. The datalogging desktop software package is used to retrieve data and groups it to produce graphs or tables.
Minimum time between logged readings
What is the minimum sample rate of data recording with the CMC99?
The minimum reading update rate that can be set for storing data is 100 msec or 10 hz.
4-20mA signal input
Is there an analog signal input for 4-20mA in the CMC99 data-logger?
Yes there are 3 available input slots and there is a choice of input card for each slot. If necessary you can fit a 16 channel 4-20mA input card in each slot providing a total of 48 independent pressure channels.
Pressure sensor inputs
Can the CMC99 log a pressure sensor for Datalogging?
Yes with the datalogging option the signal from the pressure sensor can be connected to the one of the analogue input channels on the rear of the instrument. The input signal can then be configured to display the pressure reading on the CMC99 display as a numerical value, graph plot over time or dial gauge indicator. The data can also be saved as a file and transferred to flash memory via the USB, ethernet or other serial interface.
6 analogue dial pressure & temperature gauges
I have a requirement for six pressure gauges, four are for pressure and two are for temperature. The gauges will be used on a compressor test rig. To reduce the noise levels we are building a cell around the test area to deaden the sound when the compressor is running. The control box will be outside on the test cell. Is there a gauge which will provide a remote interface so that the display can be mounted and read outside the test cell?
The approach we would suggest is to use 4 remote pressure sensors and 2 temperature sensors and feed each signal wire into a CMC99 multichannel indicator. This low or high voltage powered indicator can be mounted into a panel on the control box. The CMC99 has a 320 x 240 pixel display which can be custom configured to show 6 virtual dial gauges, all indicating the reading level of each sensor at the same time.
Reading differential pressure from 2 pressure sensors
I am searching for a digital indicator which can do the maths between 2 channels to create a differential pressure (DP) reading, what do you suggest?
The CMC99 is a multi-sensor input digital readout which includes as standard the ability to create measurement display channels by applying a maths function to specific sensor inputs. This can be configured via the front panel set-up menu screen as shown in the image below.
Logging barometric pressure inside multiple environmental chambers
I run an environmental test lab and I need to simulate altitude over the barometric range of 500 to 1030 hPa in a number of environmental chambers that are located in the lab. I would like to monitor the pressure in each vessel and feed the pressure readings into a central logger where we can display real time baro changes and store results for later analysis on a computer. Please suggest a possible instrument that would fit my requirements.
We would suggest the DMP331 which can be scaled to 500 to 1,030 mbar absolute, and the CMC99 which has multiple channels that can be configured to display the trends of multiple channel inputs, store the data for upload and provide a real time stream of data via ethernet, RS485 or RS232.
Purpose of Ethernet connection
What is the Ethernet connection used for that comes with the Advanced Communications Module (ACM) on the CMC99 controller and datalogger?
The Ethernet connection allows you to connect the CMC99 to a network and access it from any PC that is connected to that network.
You can upload logged data that is stored inside the CMC99 via the DAQ manager software.
You can also obtain readings in real-time in a basic format via a web browser such as Internet Explorer, Firefox or Google Chrome by typing the IP address allocated to the CMC99 on the network.
In the future it will also be possible for users to create their own webpages via an applet to display real-time data.
Configuration access interface
Can the setup of the CMC-99 controller be configured via the DAQ Manager software or is it only possible via the front panel access?
Configuration is carried out via the front panel, however you can plug a keyboard and mouse into the USB device ports and front usb slot which makes it easier to navigate the configuration menus.
Viewing charts and tables of logged data
Can you display tables and charts of logged data on the touchscreen of the CMC99 datalogging controller or is it only possible on a PC?
The display can be configured to show a chart view which rolls at 12 minute cycles which provides some historic data, but the PC interface and logging software is the intended way to view and analyse the logged data.
Is the CMC99 controller ready for datalogging as standard or is there an activation option?
You will need to select the license key option when ordering the instrument to activate the data logging function. Once activated you can data log any group of input channels from a minimum interval of 0.1 second up to 3600 hours as a sample rate.
Data-logging up to 40,000 psi
Can you tell me what I need to be able to operate up to 40,000 psi?
We would suggest the DMP304 which is a high range pressure sensor which would cover measuring up to 40,000 psi, combined with the CMC99.
2 input channels for reading temperature & %RH sensors
Will the CMC99 accept 2 inputs of 0-10v dc or 4-20mA to display temperature and %RH? The application is for installation in a clean room environment and would need to be IP65 rated. The display will be mounted on a stainless steel enclosure.
Yes the CMC99 is fully configurable and can accept multiple inputs from either 0 to 10Vdc or 4 to 20mA which can be converted into temperature or relative humidity engineering units. Both input channels can be displayed on the display simultaneously. There is also the option for increasing the front panel protection to IP65.
Multi-channel indicator for 6 analog input (4-20mA)
We are looking for a panel mount multi-channel indicator for 6 analog input (4-20mA), would the CMC99 be suitable?
Yes, you can select one input card for the CMC-99 which has 8 volt and 8 current inputs to handle 6 individual 4-20mA input at the same time. You can also display all 6 input readings simultaneously on the display screen.
