Details

The T3511 is a web based temperature and humidity monitor, with LCD display and a single senor with a probe.

The probed sensor is partiicularly useful, in that it allows the user to place the sensor in different locations from time to time. It also allows our customers to monitor area and positions that have a small cavity.

Supplied with a traceable calibration certificate, the T3511 comes with a 1m temperature and humidity sensor, with other lengthsbeing available on request.

How it works

This product needs to be connected to an Ethernet port in your building. Power the unit up, connect to an Ethernet port, make sure the sensor(s), if external, are connected and use our free software to locate the device on your web browser. The instruction set shows you how to do this.

Once located, you can use the web browser software to configure this unit with desired sensor values, name sensors and email address that needs to see the alarm.

Software

All configuration software is free.

If you are using many of these parts or other parts in this family, we propose that you use the DBS software monitor (available in software and downloads tab). The DBS software monitor allows you to monitor a number of units in one place on your server or PC, and store all data history automatically on to your server and analyse when required.

Specifications

Modes of Communication

Modbus TCP: Modbus TCP protocol enables to read measured values, set alarm limits, adjust the probe.
Telnet: -Port 9999 enables to set alarm limits (lower, upper limits, hysteresis for measured values and time delay), e-mail addresses, SNMP addresses, probe description, refresh of www pages (10s to 65535s), set storing interval to history (10s to 65535s), enable each communication channel. Capacity of the history memory is 100 sets of temperature, humidity, pressure + computed values. Password protection of this port is enabled. Automatic IP address assignment from DHCP server is also enabled.
WWW pages: User selectable design of www pages enabling to display curve of measurement history. User can design the look of www pages and temperature, humidity, pressure + computed values history.
SNMP: It is possible to read actual values and alarm limits. In case of alarm creation warning message (trap) is sent to addresses defined by the user (maximum three addresses).
SOAP: Online transmitter enables to send actual measured data in the format of SOAP message to selected web server in preset interval 10-65535 s.

Online transmitter enables to monitor measured values. In case of exceeding of adjusted limits warning message can be sent to specified addresses. There are the following options of alarm indication:

Alarm Indication Options

E-mail: In case of alarm creation warning e-mail message is sent to addresses defined by the user (maximum three addresses) or via e-mail to SMS message. Basic SMTP authentication is supported.
SNMP: In case of exceeding of adjusted temperature, humidity, pressure + computed value limits alarm is activated and warning trap is sent to user specified IP addresses (maximum 3 addresses).
WWW pages: In case of exceeding of adjusted temperature, humidity, pressure + computed value limits active alarm is displayed on www page.
syslog: Online transmitter enables to send text messages to selected syslog server after different events appear. E.g. after transmitter restart, alarm activation, communication error with SNTP, after firmware change, after alarm termination, after communication error with SOAP server.

Synchronizing of time and record to www table and measured values history is enabled by SNTP via Internet

Dimensions of the case (W x H x D): 88 x 73 x 39,5 mm
