The PD170 detectors offer all the standard features of the PD130 range plus additional features and functionality to simplify installation and improve performance and reliability.
This single channel vehicle detector can be used to identify the presence of vehicles by means of an inductive loop buried under the road and can be used for almost any vehicle detection application. It includes many new features including AFS (Automatic Frequency Selection), which ensures less set up time, thereby simplifying the installation of complex multilane access control sites. It also ensures a low cost of ownership.
PD170 detectors, part of the 7 series, are CE tested and approved and come with a 5-year manufacturer’s warranty.
|Self-tuning range:||20μH to 1500μH|
|Sensitivity:||Four adjustable on the front panel:
Ranging from 0.01% DL/L to 0.1% DL/L
ASB (Automatic Sensitivity Boost) selectable
|Frequency:||Automatic Frequency Select (AFS) and separate option to select from 4 frequencies
(Frequency determined by loop geometry)
|Response Time:||200 – 300ms|
|Pulse Output Duration:||User selectable to either 150ms or 250ms|
|Presence Method:||Permanent or Limited|
|Presence Time:||Permanent presence (infinite)
Limited presence - time dependant upon level of detect and environmental conditions
|Drift Compensation:||Incorporated automatic method of tracking changes caused by environmental conditions at a rate approximating 1% DL/L per minute (Presence Time)|
|Anti-locking (Positive DL/L):||Incorporated algorithm accommodates the influence of positive inductance changes, the anti-lock time is 4 seconds|
|Power Fail Memory:||Permanently on; Reset available to clear stored data|
|Recovery Time:||Set to 80ms allowing for the detector to return to the ambient mode in preparation for arrival of the next detection|
|Output Configuration:||Two output relays:
Relay 1 operates as a presence relay, activated on detect
Relay 2 operates as a pulse relay, activated on an event determined by the switches
|Protection:||Loop isolation transformer, zener diode clamping on loop input, gas discharge tube|
|Power:||PD174: 12 to 24 V +/- 10% (AC/DC)
PD172: 230V +/- 10% AC
