Reliable Radiation Monitoring for Military, Mobile, and Civilian Applications
OPTOKON LMRS-1A and LMRS-TD are highly reliable nuclear and ionizing radiation sensors designed for detecting, measuring, and monitoring radiation levels in real time.
They are key components of the Nuclear Radiation System LMRG-8 but can also operate as standalone devices integrated into other computer or communication platforms.
Thanks to their rugged design, the sensors can be installed inside or outside vehicles, as well as on aviation platforms, UAVs, drones, or stationary stations.

FAQ — Frequently Asked Questions
1. What is the difference between LMRS-1A and LMRS-TD?
- LMRS-1A — a basic radiation detector (gamma/beta radiation)
- LMRS-TD — an enhanced version with a thermodosimeter for accumulated dose tracking.
2. Can the sensors be integrated into systems other than LMRG-8?
Yes. Both models have open communication interfaces (Ethernet, RS-485, CAN), allowing easy integration into any computer or SCADA platform.
3. Are the sensors suitable for use on drones?
Yes.
LMRS-1A and LMRS-TD feature a lightweight, rugged, and sealed design specifically engineered for aviation platforms (UAV, UGV).
4. What is the protection level of the housing?
The housing meets MIL-STD-810G standards—protection against dust, moisture, shocks, vibrations, and temperature fluctuations.
5. How are power and data transmission handled?
The sensors are powered by 10–36 V DC and can transmit data in real time via Ethernet, RS-485, or CAN bus.
6. Can the devices be used in civilian monitoring applications?
Yes. LMRS sensors are suitable for civil protection, energy, environmental monitoring, and any facilities that require continuous radiation control.
7. Are data preserved if the connection is lost?
Yes, LMRS-TD has a built-in memory buffer that stores data for later transmission.
