This makes them useful for the analysis and detection of teleseismic earthquakes as well as techniques involving ambient noise. However, they are also well-suited for measuring high-frequency energy, limited only by the Nyquist frequency of the [[data logger>>doc:Instrumentation.ANU LPR-200.WebHome]]'s sampling rate. The downside to broadband sensors is usually their cost, size, and fragility relative to short-period sensors. 8 8 9 -* staff and facilities available at your institute 10 -* shipping method (air, sea, road/rail) 11 -* access for inspectors en route (e.g., customs or dangerous goods). 9 +== Nanometrics == 12 12 13 - Inmost instances,we providedimensionsfortheborrowertoquote andbook freightdirectlywiththeirpreferredcarrier. This simplifiesbillingand insurance arrangements.However,we willstillassist with technical detailsthroughoutyourbooking ifneeded.11 +Currently, 4 kinds of nanometric broadband seismic sensors are available. The Trillium Compact 120s, Trillium Compact 20s, Trillium Compact Posthole, and most recently, the Trillium Compact Horizon. These seismometers are ideal for long-term deployments of multiple months. All of these seismometers are compatible with the LPR-200 and TSAWR loggers and are designed for low energy consumption. 14 14 15 - Directionsforreturn freight willbe provided with yourSupply Agreement.13 +=== Trillium Compact 120s === 16 16 17 - ----15 +The Trillium Compact 120s has sensitivity band between 120 seconds and 100 Hz but is prone to corrosion when buried for long periods.

Brush off as much dirt as possible. 30 -1. Inspect crevices for insects, eggs, seeds, etc. 31 -1. Wipe instruments clean if placing directly into foam or textile cases. 27 +The Trillium Compact Posthole is designed with a robust casing allowing it to be deployed via direct-burial without a vault or protective case. It does NOT have leveling feet nor a bubble (**bring your own!**), nor can its mass be rebalanced. The cable is also quite a bit more stiff so may require burial at an increased depth. If installed inside a vault, the cable may also unbalance the sensor if left by itself. The instrument response is identical to a Trillium Compact 120. 32 32 33 - **Before packingequipmentfor return:**29 +For more information, refer to the [[Nanometrics Trillium Compact PH information sheet>>https://nanometrics.ca/hubfs/Downloads/Data%20Sheets/trillium_compact_ph.pdf?hsLang=en-ca]] 34 34 35 -1.

Let everything dry well before packing. 31 +=== Trillium Compact Horizon === 39 39 40 - Note:Our technicianswill cleanconnectorsand tougherstains in the lab.33 +The Trillium Compact Horizon is sort of a mix between the Posthole and Compact 120, ideal for shallow direct bury deployments or instances where packing weight and size is an important consideration.

They are generally defined as any instrument that begins to **lose sensitivity at periods larger than 10 seconds**. They tend to be smaller and more mechanically robust to broadband sensors. 49 49 50 - **Howcleanis clean enough?**43 +=== Lennartz Electronic LE-3D Lite (MkII) === 51 51 52 - Wewillpostsomeexamplephotos soonfromour 2025/2026summerbacklog,indicating thestandardsconsideredreasonableforlow-riskreturns.45 +The LE-3D Lite are small, robust, short period sensors with a a corner period of 1 second. 53 53 54 -There will often be a few missed spots, which is why we do a second check before testing, and a third check before packing for the next experiment. 47 +=== SmartSolo Short periods === 48 + 49 +Two types of SmartSolo brand seismometers are currently available, one of which is a short-period seismometer with corner frequency of 5 Hz.
