Introduction
IRD Mechanalysis Limited has been a Condition Monitoring Solutions provider to the World since 1962. Also commonly referred to as 'IRD' - the Solutions range from Portable Instruments to Online Systems for Vibration, Temperature, Speed, Gap, Bearing and Turbine Monitoring. IRD provides Wall Mountable Machinery Protection Transmitters (MPT) - IRD7100 that can do 24x7, 365 days Gap Monitoring. The salient features of this system are:
- Can be Wall Mounted onto any Support Structure
- Can be built in Single, Dual and Four Channel variants
- Can be built with Al Die Cast, Polycarbonate, ABS, CRCA or other enclosures - as per project requirements
- Provides Live Gap display, 4-20 mA output, 0-5 V DC output, Forward and Reverse Alarm and Trip Relay Contacts for each channel

Single Channel Gap Transmitter for a Turbine
Seen here is IRD7100 Gap Transmitter within an ABS Enclosure of 350 x 300 x 205 mm size. It is fitted with Live Display that is easy to read even from a Distance. The Transmitter has user adjustable setpoint for Forward Alarm, Forward Trip, Reverse Alarm and Reverse Trip. The Sensor is a Non-Contact Eddy Current based Sensor having a Nominal Sensitivity of 8V/mm. The enclosure is large enough to accommodate the Sensor's Driver - thereby eliminating needs of a separate Junction Box to house the Driver.
The system provides 4-20 mA proportional to +/- 1 mm Gap. The site is a Chemical Manufacturing company in West Bengal and the system is protecting a Turbine deployed for Captive Power requirements of the End User.
Calibration and Quality Assurance
Each Gap Transmitter that we make goes through several Calibration checks and Quality Assurance checks before Dispatch - thereby ensuring peace of mind for User at time of use. The Calibration checks and Quality Assurance checks that each Gap Transmitter goes through are:
- 100 hours of Burn-In test prior to commencement of Calibration checks
- Simulated Sensor Input using variable DC Power Supply. The Display, 4-20 mA, 0-5 V and Relay Contacts are checked at 0, 25, 50, 75 and 100% of Full Scale using a simulated DC Voltage Input from a variable source
- Actual Sensor Input and variation of Gap. The Display, 4-20 mA, 0-5 V and Relay Contacts are checked again at 0, 25, 50, 75 and 100% of Full scale - with the difference being the use of Actual Sensor and an apparatus that allows to change the Gap to Precise values
