African Petrochemicals is South Africa’s leading bi-monthly print and digital trade magazine for the past 15 years. Featuring all the latest petrochemical industry news, special reports, technological advances etc.


INSTROTECH, local representative of Monitran, is promoting their General Purpose Monitoring Sensors, for use with PLC’s and other industrial controllers. They provide users with a continuous output of vibration usually as a 4-20mA signal. Changes in the monitor signal will allow the user to spot vibration changes in the part of the machine to which the sensor is attached. Rapid changes accompany such conditions as machinery working loose from its mountings, fan blade malfunction, bearing failure all of which require immediate attention and machine shutdown to avoid widespread damage and loss of machine time. If the signal is logged at regular intervals, gradually increasing vibration indicates wear in the part of the machine where the sensor is fitted calling for replacement or detailed study with a portable vibration analyser.


This type of information is required in a wide range of environments so while the basic output is common to all sensors in this category there are many variations allowing them to be used in those different environments ranging from:
• standard industrial conditions
• submersible and long term wet operation
• approved under ATEX, IECEx and ANZEx for use in hazardous areas

The long standing 1185/C series is tried and trusted. It’s a general purpose, top-entry velocity transducer with DC output, made from robust stainless steel throughout for continuous vibration monitoring in harsh environments. The unit is sealed to IP67 with industry standard two-wire 4-20mA output proportional to sensor range that can connect directly to PLC, DCS and other industrial controllers.

The 1185I /C model is ATEX and IECEx Group I & II certified. It has all of the 1185’s components with integral stainless overbraided ETFE cable and is available with a wide range of mountings.

The 1185W model is a submersible, for harsh underwater environments and areas with constant moisture or condensation. Includes integral heavy duty polyurethane cable and is sealed to IP68 and is available with a wide range of mountings. The 1185IW is ATEX and IECEx Group I & II certified.
