Siemens Expands Lesman's Exclusive Territory for Process Instrumentation

Lesman Instrument Company has been a premiere Siemens process instrumentation representative in Illinois, Wisconsin, and Northwest Indiana since 1996. During that time, we have worked hard to deliver high quality instrumentation and support to our Siemens, Milltronics, Moore Products, Danfoss Flow, Mass Dynamics, and Controlotron customers.

Given that dedication and success, Siemens has named Lesman as exclusive instrumentation representative for most of Indiana (excluding the areas around Cincinnati OH), Eastern Missouri, and the Paducah area of Kentucky. Siemens has also expanded Lesman's territory to include all of the state of Illinois.

Lesman will now serve as your exclusive local representative for the following products

Our commitment to serving Siemens customers is evident in our ongoing educational programs, local support, and the full offering of Siemens content available through our website,, where you’ll find product brochures, specifications, user manuals, support files, training videos, and more.

Lesman’s outside sales team has expanded to better serve our new customers. Support includes local technical sales contacts for our Indianapolis and St. Louis area customers. Their efforts will be supported through Lesman’s headquarters in Bensenville, IL, which houses the inside sales team, application and product specialists, purchasing and expediting, and the corporate training center.

Please update your vendor records
Customers in Lesman's new service area will need to update their Siemens vendor record to reflect the new representative, and Siemens new name. Please change any records you have reflecting Siemens, Siemens Energy and Automation, or Siemens Process Instruments to the following: Siemens Industry Inc, care of Lesman Instrument Company.

Please note, neither Siemens nor Lesman's billing address has changed as a result of this territory shift.
