▲ VLTS – stores data, prints and alerts up to 4 channels. Temperature/ humidity/ 4-20 and
contact switching.
▲ VLTSC – stores, prints and alerts with a SIM slot and a GSM cellular modem for viewing
and backing up data, remote settings, GPS geolocation, SMS and email alerts.
▲ Temperature sensor – temperature sensor only (electronic)
▲ Humid/Temp – temperature and humidity sensor (in one body)
▲ Humidity sensor – configuring the temperature and humidity sensor to measure
humidity only.
▲ Contact switch sensor – on/off sensor between wires 1-6, blue and white.
▲ 4-20/0-20mA/0-5V/0-10V sensor – Analog transducer sensor corresponding to
representative figure.
▲ USB – standard for connecting computer peripherals for data transfer or storage.
▲ Micro-SD – A miniature memory card for transferring or storing data.
In addition, in the VLTSC model only:
▲ Micro-SIM – card for communication in a cellular network.
▲ GPS – geolocation system on a map.
▲ GSM - standard for cellular communication networks.
▲ SMS – messaging service (text) on GSM networks to a mobile phone.
The VLTS devices record, store and print up to 35,040 readings at predefined time intervals for
4 data sources or 4 cooling systems simultaneously. The VLTS device triggers an alarm when
the temperature/reading value rises or falls below the set range. The alarm can operate
immediately when the reading is off the set range, or after the reading stays out of the set
range for a set time (delay). The VLTS device enables various printing modes, including the
ability to store data in internal memory and also on a memory card or disk-on-key, and it sends
an alarm to an external device through a connection to the alarm contacts on the device.
In a VLTSC device, after connecting the GSM/GPS antenna and installing a compatible micro-
SIM (not included), the data can be sent by cellular communication for backup and viewing
through a compatible web portal, adjust settings remotely, view the unit
’ s location on a map
and automatically alert by SMS up to 5 recipients and similarly, through the email portal, alert
up to 5 recipients through the e-mail portal.
The sensors ’ reading range
Temperature range – with temperature sensor: - 40ºC to +130ºC at ±0.5ºC accuracy.
Temperature range – with temperature and humidity sensor: -40ºC to +130ºC at ±0.5ºC
accuracy.
Relative humidity range – with temperature and humidity sensor: 0% to 100%, 10%-90% RH
at ±2% accuracy.
at the rest of the range: 90.1%-100% / 0-9.9% RH at ±4% accuracy.
Contact sensor
– indicates on/off switch status.
Voltage sensor – analog Transducer 0~10, 5~10 Vdc and correspondence to representative
value, ± 0.5 F.S.
Current Sensor – analog Transducer 0~10, 4~20 Adc and correspondence to representative
value, ± 0.5 F.S.
Response time – sensor: voltage and current: 1 second; for contact sensor: detects change of
state up to 10 seconds.
