Harvestree Measurements Technical Reference

← Measurement ports

Conventions

• Telemetry: values produced at the end of one measurement pass (LoRaWAN, Modbus, or local service interface, depending on device mode).
• Changing the measurement type on a port clears that port’s calibration and alarm settings for that port.
• Pass duration is the duration of one acquisition; how often it runs (application period, radio, sleep) is configured separately — see user Configuration / Harvestree Operation Reference.
• Energy: figures in this document are measurement-pass budgets only (they exclude LoRaWAN radio). Per-pass use varies a lot with measurement type and settings (delay, oversampling, etc.); each section gives typical pass duration and charge examples. Radio uplink consumption and cycle scheduling are covered in Harvestree Operation Reference. For overall energy and autonomy planning, contact MOIZ or your supplier for application support.
• Analog conditioning: most analog ports include hardware low-pass filtering on the conditioner, designed to attenuate high-frequency interference before digitization (implementation and cutoff depend on the measurement type). Further sample processing reduces what still passes the filter; see Rejection under How the reading is produced.
• How readings are built: after a port is selected, the electronics settle, then optionally wait (delay you configure). Each section under How the reading is produced uses the same bullet labels (Settling, Rejection, Spikes or How the value is found, Still pay attention to, Calibration / Output / Behavior where applicable). Wording is harmonized within each acquisition family (DC analog, AC, digital probe, vibration, contact).

4–20 mA loop

Compatible probes

• MOIZ-qualified 4–20 mA loop cabling with embedded 120 Ω shunt for externally powered loops (device does not power the loop): Catalog. Cable use is required for compatibility. Third-party cabling or loop wiring require written MOIZ approval.
• If the embedded 120 Ω burden is insufficient for the selected 4–20 mA sensor/transmitter, add external loop load as required by the sensor compliance specification.

Physical quantity

• Primary quantity in configured engineering units (default: mA from the shunt current).

Outputs and quantization

Alarms are evaluated on corrected primary quantity (after calibration).

Resolution on the link

• float32 primary quantity.
• Digitization: 12-bit ADC.

Global accuracy

• ± 0.02 mA (measurement chain) + sensor/transmitter accuracy.

How the reading is produced

• Settling — ~20 ms after the port is selected; optional extra wait up to ~1 s (configurable).
• Rejection — RC low-pass on the conditioner rolls off high-frequency interference; 20–100 ms integration (oversampling) reduces supply harmonic interference.
• Spikes — The most extreme 10% of samples in the window are not used in the average.
• Still pay attention to — Loop supply stability, wiring resistance, ground differences, slow drift during the measurement window, and interference that lasts longer than the averaging time.
• Output — Current from shunt voltage (I = V / 120 Ω).
• Calibration — None (raw shunt-derived mA), linear mapping (guided parameters), or lookup table (manual curve).

Typical pass duration

• (20 ms + delay) + (20 ms × oversampling factor).

Energy

How the reading is produced

Vibration

Analog 1-axis vibration

Compatible use

• Single-axis vibration measurement; compatible products are listed in the Catalog.

Physical quantity

• LF: spectral RMS as velocity (mm/s) over 10 Hz–1 kHz.
• HF: spectral RMS as acceleration (m/s²) over 2 kHz–10 kHz.
• Sub-band energy ratios (LF three, HF two) for relative band content.

Outputs and quantization

Ratios are telemetry only (not alarm inputs).

Alarms apply only to LF and HF RMS (corrected), not to ratio bytes.

Resolution on the link

• LF 3.2 kHz, HF 32 kHz; 2048-point spectra after warm-up; Hann window. Telemetry scaling as in the table above.

Global accuracy

• LF RMS ± 5 %; HF RMS ± 5 %

How the reading is produced

• Settling — ~20 ms after the port is selected; optional extra wait up to ~1 s (configurable).
• Rejection — Low-pass on the vibration path (cutoff tracks sampling rate) rolls off content above the useful acquisition band.
• How the value is found — Spectral integration reports energy in configured low- and high-frequency ranges.
• Still pay attention to — Mounting, cable routing, temperature, and band limits vs. the fault you are monitoring.
• Calibration — Sensitivity, offset, optional band edges and delay; optional time trace or spectrum in host software.

Typical pass duration

• (20 ms + delay) + ~1 s spectral acquisition (LF then HF bands).

Energy

• Per pass (calculated budget): approximately 10 mC to 20 mC over the typical timing range above (equivalent to about 0.00278 to 0.00556 mAh per pass).

Alarms

• Quantities: corrected LF RMS and corrected HF RMS in configured engineering units.

Calibration

• Acquisition timing: delay before spectral acquisition.
• Primary quantity calibration (overall channel): sensitivity and offset
• Spectral partitioning: LF / HF sub-band edges overrides

Dry contacts

Dry contact (synchronous)

Physical quantity

• Contact state (open / closed) with defined excitation on the port.

Outputs and quantization

How the reading is produced

• Settling — ~20 ms after the port is selected; optional extra wait up to ~1 s (configurable).
• Rejection — Hardware filtering and debounce on the contact path.
• Output — One sampled open / closed state per pass; logic can be inverted in calibration.
• Still pay attention to — Contact bounce, wet or high-resistance contacts, and cable capacitance on long runs.

Global accuracy

• N/A (discrete open / closed; alarms on 0/1 logic)

Typical pass duration

• ~20 ms + delay (no multi-sample averaging).

Energy

• Per pass (calculated budget): approximately 0.1 mC to 5.1 mC over the typical timing range above (equivalent to about 0.00003 to 0.00142 mAh per pass).

Alarms

• Quantity: open / closed state, exposed to the threshold engine as a numeric value (0/1 or equivalent) for High / Low / In range / Out of range rules.

Calibration

• Acquisition timing: sense delay
• Primary quantity calibration: invert logical state

Dry contacts — asynchronous

Asynchronous dry-contact trigger

This path is a contact trigger for ALARM mode, not a scheduled measurement type like the ports above.

Purpose

• Wake / trigger the product on a dry-contact edge (rising or falling), then monitor the contact until it returns to normal.
• For a sampled open/closed value on each application period, use § Dry contact (synchronous) instead.

Availability and configuration

• Usable only when application mode is ALARM (not in normal periodic measurement scheduling).
• Per port: enable the async alarm trigger and choose rising or falling edge (plus alarm flags as needed).
• No unified port calibration, no logical inversion, and no per-port measurement alarm table like synchronous dry contact.

Output

• When read for telemetry or servicing: uint8 0 = open, 1 = closed (same encoding as synchronous dry contact).

How the reading is produced

• Rejection — Hardware filtering and debounce on the contact input.
• Behavior — The configured edge into the alarm-active contact state starts the ALARM flow; that state is then checked on each alarm-cycle wake until the contact is back to normal (no re-trigger on further edges during the episode).
• Still pay attention to — Noise on long cables, supply coupling, and false triggers from vibration or EMI.

Energy

• Passive path current on the contact circuit: approximately 1 µA open, 330 µA closed.
