DIN Rail mounting, this industrial quad band GSM device can monitor up to 12 input/outputs, and send alarms, data, status or action messages to multiple recipients via SMS. Sentry Telemetry’s Windows-based software provides remote configuration of all alarm variables, message recipients' etc. Alarms can be sent to mobile phones, pagers and PC’s with a modem.

SentryGSM3DLogger
SentryGSM3DLogger is an advanced, low cost solution for data logging with the key feature being the email output capability. This device is used mainly for meter reading, with data exported daily or weekly to a web server.
DIN Rail mounting, this industrial quad band GSM device can monitor and data log up to 12 inputs, send alarms via SMS, plus export data logged information by email or to a web based application server for storage and display. Sentry Telemetry’s Windows-based software provides remote configuration of all variables, message recipients' etc.

SentryGSM3DControl
SentryGSM3DControl provides a reliable, low cost solution for a wide range of control, monitoring and alarm messaging applications. DIN Rail mounting, this industrial quad band GSM device can monitor, control and program up to 11 input/outputs, and send alarms, data, status or action messages to multiple recipients via SMS. Relay outputs can be configured to switch and/or operate external devices; Sentry Telemetry’s Windows-based software provides remote configuration of all variables, message recipients' etc.
Already successfully integrated into client applications, the SentryGSM3Control offers a cost-effective solution to OEMs, instrumentation, sensor and meter companies, MCC manufacturers, industry and factories. Through our in-house application engineering and web hosting services, we can develop custom telemetry and data management solutions.

SentryGSM3DKey building monitoring
SentryGSM3DKey is an advanced, low cost solution for remote gate opening and door access security.
DIN Rail mounting, this industrial quad band GSM device can analyse a mobile phone's CLID (calling Line ID) and allow or deny access based upon it. Simple to use, each mobile number registered within the unit's memory (up to 4000 numbers) becomes a key. As the call is not answered there is no cost to the individual(s) using the system. Without no need for entry cards, or for expensive remote controls to be issued to workers or relatives, the SentryGSMDKey is the easiest - and probably the cheapest - long-term gate and door access system on the market.
Sentry Telemetry’s Windows-based software provides remote management of multiple sites for heavy users or, for home/light use, the system can be configured from a mobile phone.

SentryRADTx
SentryRADTx provides a reliable, low cost solution to a wide range of wireless monitoring and alarm applications. Offering a variety of sensors and mounting options (including the innovative inductive MAG) the ATEX approved SentryRAD range may be used to collect and wirelessly send data to SentryPSTN, SentryGSM2E, SentryGSM3D and RS485/232 units.

Sentry sensors and gauges
Sentry has designed a number of unique sensors which, together with our partners, allows us to provide measurement and monitoring solutions for a wide range of applications. These sensors may be wired to other Sentry products or, through the use of our SentryRADTx products, connected wirelessly.

Sentry RS232/4-20mA PCB
The SentryRS232 PCB provides a reliable, low cost solution for a wide range of wireless monitoring and alarm applications. A wireless receiver, the PCB has serial, digital and 4 to 20mA outputs.
