  • For calibration, this product requires an ILA-PGMD-A
SKU: ILA-SSBG- Category:


Housed in an IP50 in-line enclosure, Mantracourt’s In-Line Amplifier (ILA) converts strain gauge or load cell inputs into a high stability 4-20 mA output.

Its small design enables it to be easily integrated into compact installations. The ILA is compatible with a wide range of inputs including strain gauges, load cells, pressure and torque transducers.

Gain and offset calibration is performed by a dual 256-step non-volatile digital potentiometer allowing fast semi-automatic calibration via Mantracourt’s proprietary custom programming module (ILA-PGM) and ILA Toolkit which is free to download (see downloads tab)

Extensive EMC filtering reduces noise for reliable and safe operation.

The ILA is available in standard sensitivities (see order info options) and can be customised to suit your requirements; simply select your sensitivity, trim range & bandwidth (MOQ applies).

Windows drivers are available for OEM calibration.

To calibrate, the ILA requires an ILA-PGMD-A programming module & proprietary ILA-CAB cable (included with ILA-PGMD).

Q. How do I power the ILA?

A. You will require a power supply of 9-32 DC

Q. How do I calibrate the ILA?

A. Digital trim pots allow for quick semi-automatic calibration which is available via use of the programmer (ILA-PGMD-A) and free Toolkit.  Note the cable (ILA-CAB-A) is included with the programmer.

Q. How do I get the software for the ILA?

A. The free ILA Toolkit software is downloadable from the Mantracourt website

Q. Is the ILA available as an OEM PCB board option as well?

A. Yes, both the ILA and programmer are available as OEM (uncased) versions.

Q. What is the warranty period on this device?

A. The ILA from Mantracourt Electronics Ltd., (‘Mantracourt’) is warranted against defective material and workmanship for a period of one (1) years from the date of dispatch.

Q. What are the dimensions of the cased ILA?

A. 84 mm x 27.5 mm x 17.5 mm

Q. Can I customise the sensitivity, bandwidth and offset trim range?

A. Yes, these are all customisable options although a MOQ of 72 applies to a customised version (and then susequent units of 24).  The standard version is 2.5 mV/V (sensitivity), DC to 10 kHz (bandwidth), ±2 %FR (offset trim range), ±8 %FR (span)

Q. What is the IP rating?

A. IP54

Q. Does this device offer EMC filtering?

A. Yes, the ILA offers extensive filtering to reduce noise for safe and reliable operation.

Q. What temperature will the ILA work in?

A. Operating temperature range: -40 to 85 ºC
​Storage temperature range:  -40 to +85 ºC

Q. Is there reverse polarity protection?

A. Yes, as well as short circuit protection, input and output protection.

Q. What are the order codes for the ILA and accessories?


ILA-SSBG-A: In-Line Bridge Amplifier

ILA-SSBX-A: In-Line Bridge Amplifier OEM Board

ILA-PGMX-A: In-Line Amplifier Programmer OEM Version

ILA-PGMD-A: In-Line Amplifier Programmer Cased

ILA-CAB-A: cable included with the programmer

ILA Toolkit: In-Line Calibration Toolkit


Q. What output is created from the ILA?

A. A high stability 4-20 mA output.

Q. Is customised branding available with the ILA?

A. Yes, it can be branded. Mantracourt will provide the supplier details for custom labels.

Q. How many load cells can be attached to the ILA?

A. Four 1500 ohm load cells

Q. Is the ILA low power?

A. Typical current drain with a 350 ohm load cell is approximately 42 mA at full scale.

e.g. when connected to a 350 Ohm load cell:-
Total current = Operating current (8mA) + Excitation current (5/350 = 14mA) + Output current (20mA FS) = 42mA FS (typical).

Q. Can I write my own software to calibrate the ILA?

A. Yes, there are drivers and instructions available to help with this.  I2C, Dot Net drivers and virtual com port.

Q. What size cables can be used with the ILA?

A. The grommets cater for cable diameters between 4 to 6 mm. Smaller diameter cables can be used at the expense of effective dust and particle sealing.
