Description:

The SensaTronics IT temperatures sensors provide multiple temperature readings for remote temperature probes. Sensors are commonly used to measure ambient air temperatures in equipment racks or other locations. Heavy-duty industrial probes are available that can be used to measure temperatures for outdoor applications.

The devices provide a read-only interface via Ethernet. A simple HTML “Get” request retrieves a delimited (non-HTML) string containing the configured names of the probes and current the temperature values. The device does not provide an interface for configuration via Ethernet; you have to connect make a serial connection directly to the device to set it up.

The CQC driver provides a read-only interface that returns the probe names and devices. There are currently two device models supporting either four or sixteen probes, and the driver will automatically determine how much data is being returned and configure the available fields appropriately.

This driver is CML based and the classes are found in the CML scope MEng.System.CQC.Drivers.SensaTronics.E4_E16.

Quirks and Limitations:

The driver only supports the HTTP/socket based connection to the device which is read-only. Configuration settings (probe names, Fahrenheit versus Celsius settings, etc.) cannot be configured through the driver.

Connection Details

The device is IP based and can be anywhere on the network. The device does not support DHCP, and must be assigned a static IP address. You must supply the IP address when configuring an instance of the driver in CQC. If you have more than one device, just load more than one instance of the driver, each talking to a different IP thermostat.

Driver Fields

This section lists the fields that the driver makes available, their types, minimum and maximum values, etc...
