Q: What types of inputs can be used?

A: Any volt free contact input such as relays, voltage sources (up to 24 volts) and NPN open collector inputs.

Q: How accurate is the measurement?

A: The worst case accuracy is stated as 0.25% at the top end of the input range i.e. 3 kHz. Just under half this error is to allow for temperature drift over the full operating temperature range of the T24-PAdevice (-40 to +85 degrees) so the accuracy in a stable temperature environment is far less. At slower input rates (down to 1Hz) the accuracy increases further down to 0.15% where 0.1% allows for temperature drift.

Q: How do I calibrate the output?

A: The T24-PA is factory calibrated to the nearest 0.25 μS which provides users with a set of predefined outputs; Hz, RPM and Period. All of these values can have a custom gain and offset applied to them, the resulting output can therefore be in whatever units or range of values you require.

Q: What is the counter, and its maximum value?

A: The counter is a counter which increments every time a pulse is detected either on rising or falling edge which can be set in the tool kit. When counting pulses the sample time and transmit intervals must be set to the same value. Low power cannot be used to ensure the input is constantly sampled. The maximum value for the counter is 4,294,967,295 at which point the counter will overflow.

Q: How do I reset the counter value of the T24-PA?

A: The counter value can be reset either by contacting the digital input to the ground or by transmitting a data packet with a defined data tag from another device, such as a T24-HA, T24-RM1 or even another T24 transmitter module.

Q: What software is provided with the T24 devices?

A: All devices are supported by the T24 Tool Kit which allows users to configure all devices from the T24 range as well as view and log data from transmitters modules in range. The software can also be downloaded directly from our website.

Q: How many devices can operate on one radio channel?

A: Many devices can operate on the same radio channel depending on the sample rate of the transmitter modules present in the system. The radio channel is capable of supporting up to 200 data packets per second.

Q: Can PC software gather data from many devices?

A: Yes, Mantracourt provides freeware for logging up to 100 inputs to one base station, in addition the free Windows DLL and COM driver can be used to gather data through a customer's own PC software.

Q: What limits the RF range of the devices?

A: Any metal surface will reflect 2.4 GHz radio waves, therefore in a sealed metal box, no RF will escape. However by providing a suitable RF window the signals will propagate out.

Q: What Frequency does the system operate on?

A: Licence free world wide 2.4GHz, although this frequency is used by other equipment, the T24 range has been tested with Bluetooth, Zigbee & WiFi devices without conflicts.

Q: Is it possible to use wireless range extenders within T24 network?

A: The T24-AR wireless range extender which can be added to the system can propagate a signal around corners and obstacles. This unit can also double the effective range.

Q: Is the system point to point?

A: Yes, however the modules may also operate in many to one (such as multiple data transmitters modules communicating with a base station) and one to many (such as a data transmitter module supplying data to multiple handhelds and displays).

Q: What sensors would these inputs cover?

A: Any sensor that provides a voltage, current or ratio metric interface can be connected to an transmitter module, including load cells, inclinometers, accelerometers, displacement LVDT, pressure, potentiometer, pulse, temperature, humidity, ph, shock.

Q: What is the communication protocol?

A: Proprietary protocol based on a 802.15.4 chip. This allows the T24 range to co-exist with Bluetooth, Zigbee & WiFi devices without conflicts.

Q: What are the sampling rates of the transmitter modules?

A: The T24 standard transmitter modules (SA, IA, VA, RA, TA, PA) sample from 0-200 updates/sec. The T24-SA fast transmitter modules are fixed at 2,000 updates/sec.

Q: What is the resolution of the transmitter modules?

A: The noise free resolution for a sample time of 10 milli-seconds or less is 15.5 bits for the T24 SA, 12.5 bits for the T24-VA, 14 bits for the VA and 12.25 bits for the T24IA.

The T24-PA’s accuracy % input error @ 1 Hz is 0.15% and for the T24 RA the accuracy is 0.01% of the full scale.

With increased sample times resolution can be increased up to 18.75 bits for the T24-SA.

Q: What is the supply voltage for the transmitter modules?

A: 3V for the transmitter modules and handheld displays. Other modules in the range take 9-36 V.

Q: How are the modules powered?

A: The ACMm is the smallest module and has a separate battery pack (T24-BB1 using 2 x AAA). The T24-ACMi is the mid size module and provides power via 2 x AA internal batteries. The T24-ACM although larger can provide power from an external power supply (5-18V) as well as 2 x D cell internal batteries which provide a higher battery capacity allowing for longer battery life.

Q: Can power be provided to a sensor?

A: Yes, all transmitter modules feature a 5V supply which is the excitation voltage used by the T24-SA strain gauge transmitter module.

Q: How is the strain gauge transmitter module calibrated?

A: The modules are factory calibrated to 2.5 mV/V which can be custom calibrated and linearised over up to 9 points by using the T24 Toolkit. The T24-SAf has fixed factory calibration and cannot be linearised.

Q: In the T24 transmitter range what is the difference between the 'i' and 'e' ?

A: The ‘i’ modules (T24-SAi, T24-SAfi, T24-VAi, T24-IAi) all feature an on chip
integrated antenna. The ‘e’ modules (T24-SAe, T24-SAfe, T24-VAe, T24-IAe) are
fitted with a miniature UFL connector which can be used with any of the antenna options available; the T24-ANTA (PCB antenna) or T24-ANTB (fixed 90 degree Whip antenna) or T24-ANTC (flexible whip antenna).

Q: How many transmitter modules can be acquired by the base stations?

A: Each base station can use one of 16 channels. From that selected channel a base station can collect data simultaneously from any number transmitter modules depending upon the frequency of readings being provided by the transmitter module.

Q: What are the input ranges of the T24 transmitter modules?

A: T24-SA 2.5mV/V calibrated strain gauge based measurement; T24-VA 0-10V, T24-IA 4-20mA, T24-TA pt100 sensor input, T24-RA potentiometer 500 to 100000 Ohms and T24-PA 0.5Hz to 3kHz.
